PSP:

PSP, full name PlayStation Portable, is a multi-functional handheld series developed by Sony Corporation of Japan, which has many functions such as games, music and video. In addition, in many fields, some terms are also abbreviated as PSP. Such as personal software process, program segment prefix of DOS operating system, etc.

PSP 1000

It was officially put on sale in June 5438+February, 2004 and has been discontinued. Sharp A[ 1]SV ultra-wide viewing angle LCD screen, 4.3 inches 16: 9 ratio, full backlight, screen resolution of 480*272 pixels, bright colors and first-class display effect. It has the ability to draw 3D polygons between PS 1 and PS2, and the corresponding surface NURBS modeling is a function that PS2 does not have, and the game screen has reached a new height of handheld games. It can play music files such as MPEG4-4 video files in ATRAC format and MP3 format. Use PCM sound source, corresponding to 3D surround sound, with wide range and good sound quality. The newly developed "UMD" CD with a diameter of 6 cm is used as game and audio-visual media, equipped with USB interface and memory stick slot, and supports wireless online function and hot spot connection to the Internet. With great potential for function expansion, Sony is a heavyweight product positioned as "Walkman of 2 1 century".

To sum up, in fact, PSP is not only a game machine, but also a comprehensive handheld multimedia entertainment terminal equipment. Due to Sony's low-cost "dumping" strategy, PSP has become the most cost-effective handheld multimedia terminal.

At present, this antique is only parallel or used. Suggest buying 3000, it has been cracked! Really cracked! (version 6.20)

PSP2000

The improved PSP released by SCE in 2007 has been discontinued.

PSP2000

With a smaller and thinner fuselage, the size is reduced by 19% and the weight is reduced by 33%. The new PSP weighs about 189g (originally 280g) and has a thickness of 18.6mm (originally 23.0 mm). In addition, Sony also increased the memory of the PSP to 64MB, and prepared a video output function for the new PSP. Through the purchased video cable, you can connect the PSP to the big screen TV and enjoy the charm of games and movies. The upgrade of the new PSP also includes built-in storage cache UMD data, which reduces the disk reading time and can be charged while USB is connected to PC or PS3 to transmit data. The detailed output interfaces are: AV composite interface, S-terminal, D-interface and color difference interface.

PSP2000( 13) PSP2000V3

TA-088v3 motherboard went on the market around August 2008. At the same time, the old PSP2000 model was discontinued, and PSP2000V3 used the new version of V3 motherboard. Previously, PSP was able to crack IPL because an employee of Sony leaked the motherboard design, so Sony adopted a new version of V3 motherboard, and PSP3000 also used V3 motherboard. Therefore, 2000V3 and 3000 cannot be completely cracked, and the self-made system cannot exist after shutdown. Due to the new anti-piracy measures, the magic battery is completely ineffective for this motherboard (the psp of this latest motherboard has fixed the preipl vulnerability on which Shendian runs, so the magic battery is completely ineffective here. There is a self-made tool "PSP ident" to check the model of the motherboard. In fact, there is a simpler way to judge, that is, turn it off (long press the power button) and then.

PSP3000

Published on June 5438+00, 2008. Compared with PSP 1000 to PSP2000, PSP2000 to PSP3000 are only slightly different.

A built-in microphone has been added to the left of the PSP logo.

-The rims of -UMD hut are made more exquisitely.

-the previous HOME button was changed to the logo button of Playstation.

-The screen of -PSP3000 will be brighter, which has changed the shortcoming that the old PSP2000 can only output game pictures with color difference or with D terminal of progressive scanning TV.

-PSP3000 has a size of169.4×18.6× 71.4 mm and a weight of 189g, which is completely unchanged from PSP2000.

Functionally, Sony PSP3000 has a memory capacity of 64MB, built-in stereo speaker and microphone, and the processor performance: PSP CPU (working frequency 1-333MHz), graphics processor FPU, VFPU (26 million floating-point operations per second), 3D graphics expansion operation, 1 IPS r 4000 32-bit kernel/kloc-0. 2MB eDRAM cache, 90 nm CMOS manufacturing process, and 165438 interface, Sony PSP3000 provides the body power input port, external power port, video/earphone/microphone port, USB port and memory stick port, which is convenient for users to link.

Colors: black, white, silvery gold, pink, blue piano black, ceramic Bai Bing can silver, rose pink smoked purple, daisy blue mint green, rough bronze mysterious silver, piano black pearl white, dancing blue shiny red, dazzling yellow green, lilac purple, turquoise blue, pink piano black, pearl white.

Note: The combined interface of PSPGo is DC power input /USB/ video output/audio input/output.

The cpu frequency is not nonlinear, but only 33, 66, 133, 222 ... because the main CPU frequency of psp is also composed of external frequency and frequency doubling.

sleep

Short-pulling the power button can temporarily interrupt the game in the current state, and use low-voltage power to store data in the memory. It only takes about 1 ~ 2 seconds to activate again. Almost no electricity is consumed during sleep. You can also set to go to sleep automatically after a period of time. In addition, when the battery is low, it will automatically go to sleep to save the battery.

Lock and close the screen

When PSP 1000, 2000, 3000 is in use, long press the light button to turn off the screen (mainly listening to music). When listening to music, you can turn down the switch and lock the PSP. At this time, all buttons are invalid and can only be restored by moving the switch. This function can be used for PSP dedicated wire control (the wire control cannot be locked).

match

Racing 4 mobile and UMD. Although the PSP has good audio and video playback capabilities, it still has the main game functions (compared with the control keys of TV remote controller or MP3 player): two upper buttons, the iconic PlayStation-style start and select keys, a digital 8-way button and an analog input. There is a row of control keys at the bottom of the screen, which can adjust the volume, music settings (control the on/off of music in the game, select psp to operate different preset balancers), screen brightness and return to the main menu.

PSP can play games by inserting a dedicated UMD. In addition, there are PSP-specific games and PlayStation games downloaded and sold in PLAYSTATION Store, which are stored in another memory stick and can be activated from there. Some software can also be tried online. PSP-200x and its subsequent products can output pictures to TV.

You can run UMD or PSP-specific games saved in Memory Stick Duo (purchased or downloaded from PS Store for trial play).

Run the UMD image saved in the memory stick Duo (ISO or CSO, the system needs to be cracked).

PSone game (that is, the original PlayStation game needs to be converted).

Homemade program games (the system needs to be cracked).

And play simulator games such as GBAN64 SFC through self-made programs (the system needs to be cracked).

film

Robot Adventure in UMD format Due to the huge storage space of UMD (about 1.8G) and the huge display screen of PSP, many film companies have launched UMD movie programs, and the price is similar to that of DVD. Companies that have released UMD movies include Disney, Warner, Twentieth Century Fox, Lionsgate Entertainment, Sony, New Line, Paramount, DreamWorks and Anchor Bay Entertainment. Animation companies such as Bandai, Geneon, FUNimation and Viz Media also plan to launch animation series such as Rolling God and Tomb, as well as Gundam Endless Waltz and Ah! My goddess and the ghost in the shell and so on.

music

You can listen to UMD and music stored in the memory stick. (Music stored in the memory stick Duo) The file format must be ATRAC3plus. MP3 and WMA atrac 3 plus (adaptive transform acoustic coding 3 Plus) use the advanced compression technology of ATRAC 3 Plus at the same time, so that the sound can be compressed efficiently while maintaining high quality; According to different file sizes and compression effects, you can choose the compression ratio of 256, 132, 105, 66, 64 or 48kbps, or you can choose the compression ratio of 256kbps, so as to compress music with similar sound quality to CD. Support wma format (must be set after authentication. Free).

videotape

You can convert the video format through a PC and store it on a PSP memory stick Duo card. The supported formats are MP4, MP4-AVC(H.264) and H-AVC(480P, H.264). These three formats are officially supported, and the suffix is MP4. Through the third-party self-made software, the video format with the suffix PMP is supported. After many updates, the format is PMP-AVC-AAC (H.264 video coding, AAC audio), and the maximum resolution is 480×272, which is the most widely spread in the network. Others, such as RMVB and AVI formats, can be played by self-made software, but the effect is not good and it is still in the testing stage.

draw

You can browse the pictures saved in the memory stick Duo through PSP. The image format can be JPEG, PNG or BMP (Gif can browse its static mode).

Surfing on the internet

You can browse the web through the wireless router connected with the Internet browser on PSP, which supports WIFI and does not support Bluetooth. (Version 2.0 and above is required). However, a wireless hotspot (or magic card) is needed. At present, wireless hotspots have not been popularized in China, but more personal access points can still be detected in the bustling city center.

videotape

PSP In 2000, Sony improved the PSP on the basis of model 1000. In addition to making the machine thinner, the most prominent highlight is the addition of video output function. This makes the PSP, which is very suitable for audio and video playback, even better.

First of all, there is no doubt that a video output line is needed to output the PSP to the TV or monitor. At present, PSP supports four kinds of video lines: component line, D-terminal line, S-terminal line and VGA line. Among the four kinds of cables, the component cable and the D-terminal cable are the best, but the D-terminal cable is an interface with a relatively small application range, which is basically only used in Japan at present, and has no use value for non-Japanese players. Therefore, it is recommended that players buy component lines when purchasing. Followed by the S-terminal line, and finally the VGA line. Generally speaking, ordinary display devices, PSP may not see the difference between these lines (although VGA lines can still see the decline in image quality), and users of corresponding home computers may be very aware of the difference in image quality between these lines. But this has nothing to do with PSP. We can leave it alone.

Secondly, it is also the best component line and D-terminal line for output content. The following are the differences between several lines of PSP content output:

camera

A handheld game machine that can enjoy fun at any time: PSP is not only a fashionable digital handheld machine that can play games, listen to music, watch movies, surf the Internet, read e-books and play simulators anytime and anywhere, but also has the functions of digital camera shooting and instant photo taking.

When PSP camera is equipped with editing software, it can support JPEG still image photography with resolution of 320× 240 ~ 1280× 960, and Motion JPEG moving image photography with resolution of 320× 240 ~ 480× 272 and 15 ~ 30 fps. In addition to the general photography function, it will also provide static timing photography and monitoring photography. The pixel is about 1.3 million.

The photographed photos or videos will be stored in MS PRO Duo memory stick, and can be browsed, edited and subject-specific effects processed through the built-in functions of the software, so that players can add various transitions, special effects, graphics, music and sound effects to the photos or videos themselves, and make photos such as photo stickers or theme movies, and output them to PC for viewing (the photo format is JPG, and the film output format is AVI).

Content GPS receiver and storage box

GPS-290 is a global positioning device (* 1) introduced by SCE (Sony Computer Entertainment Company), and 290 is its serial number. After the dedicated camera of PSP, GPS will once again expand the world of PSP. From the practical tools and software and some game ideas that may be unrealistic in the past, PSP's dedicated GPS global positioning device will make more impossible possible. Although PSP can also use other GPS devices (*2), the official GPS-290 is simpler to use and the price is undoubtedly better than the general GPS receiver.

Like the microphone and camera in the past, the GPS GPS dedicated for PSP is connected through the USB interface on the upper part of PSP, the transparent acrylic panel on the upper part plays the role of antenna reception, and the left side is fixed with screws.

1: GPS, which is the global positioning system. Established by the US Army, Navy and Air Force in the 1970s, it can provide accurate positioning, speed measurement and high-precision time standard for most areas (98%) of the earth's surface. The system consists of 24 GPS satellites in space; There are 1 master control stations, 3 data injection stations and 5 monitoring stations on the ground, and the client is a GPS receiver. At least four satellites are needed to quickly determine the position and height of the client on the earth; The more satellites that can be connected, the more accurate the decoded position will be. (Civil positioning is currently free)

GPS system has the following advantages: all weather, not affected by any weather; Global coverage (up to 98%); High-precision three-dimensional constant-speed timing; Fast, time-saving and efficient; Wide range of uses and diverse functions; Movable positioning; Different from the double-star positioning system, the receiver does not need to send out any signals during use, which increases the concealment and improves its military application efficiency.

2. Use other types of USB devices on the PSP, generally using DIY GPS cable (requiring hands-on player operation), and then connecting the cable to other GPS for use on the PSP. Unofficial GPS uses unofficial programs to observe maps or locate.

cpu

Play Station Portable

High-performance CPU and DRAM embedded in CPU kernel

In order to make the 3D function of PSP close to the level of PS2, Sony equipped PSP with two R4000 CPU cores. R4000 is a RISC (Reduced Instruction Set) processor developed by MIPS Technology Company. The frequency of one of the two R4000 PSP CPU cores is 333MHZ. It has a 128BIT system bus (note: the connection bus with memory or external circuits), through which it communicates with media engine, main memory and graphics core1&:2. VME (Virtual Mobile Engine) and DMAC. The whole data transmission operation is under the control of DMAC-memory direct access controller. In the process of data transmission, CPU can do other work besides doing some processing at the beginning and end of data transmission. In this way, most of the time, CPU and input and output are running in parallel.

Therefore, the efficiency of the whole computer system is greatly improved. Its function in PSP is to connect CPU with optical disk system and I/O devices, and to read and process the information of optical disk system and I/O devices (such as handles, display screens and U** interfaces are I/O devices). ] connection. The PSP CPU Core 1 integrates I-Cache (the specific capacity of instruction cache is unknown), D-Cache (the specific capacity of data cache is unknown), FPU and VFPU (vector unit). The 3D computing power of PSP CPU core mainly comes from two vector units, FPU and VFPU. Its floating-point operation ability has reached 2.6 gflops (the value when 3D-CG extended instruction -3D extended instruction set is involved in the work), which is already the floating-point operation amount of P3 733 (the value when SEE instruction set is added is 2.93GFLOPS(SSE)). Many people say that PS2 GS supports too few special effects. Why are there so many unsupported special effects in the game? In fact, due to the contributions of FPU and VUO+VU 1 of EE, the total floating-point computing power of EE has reached 6.2 GFLOPS. The VFPU of PSP is equivalent to VUO+VU 1 of EE, so don't look at the graphics core, it doesn't support many special effects. However, we can rely on FPU and VFPU to achieve unsupported special effects. Many people say why not support it in the graphics kernel, because the current technology has not enabled GPU to simulate special effects. Even nVIDIA's GeForce series or ATI's RADEON series only control their inherent special effects through programming. For newly added special effects, such as adding new special effects to the new DIRECTX version, it is necessary to replace the graphics card supporting this DIRECTX version. The game machine cannot be replaced every 6-8 months like the graphics card of a PC. Moreover, although the floating-point operation of GPU is higher than that of CPU, it is limited. So Sony's choice is still very wise-using a GPU with high floating-point operation to simulate special effects.

PSP CPU core is used for 3D operations such as polygon generation in advance to simulate some special effects. Its core integrates 30MB DRAM main memory, which can accommodate more polygon data and high-resolution textures. Main memory bandwidth is 2.6 GB/ sec. The PSP CPU core uses its 128-bit bus to connect DRAM, giving full play to the super-high performance of PSP CPU core (note: although it is embedded memory, it still needs a bus to connect it). The advantage of embedded memory is that CPU can directly access the memory, reduce the response time of the memory and provide high bandwidth. Another R4000 is called Media Engine-Media Engine. As the name implies, it does media decompression, sound processing and I/O management, not 3D operation. Therefore, it cannot participate in 3D operation. It is wrong for many websites to say that two CPUs can cooperate with 3D operation. Because it doesn't integrate FPU VFPU (don't rule out my misunderstanding). Its frequency is also 333MHZ, and it shares 128BIT front-end bus with PSP CPU core * *, and it is embedded with 2MB DRAM with a bandwidth of 2.6 GB/ sec. Mainly used as media decompression buffer and audio memory. This is the way to decompress MPEG4 4.

Graphic core

The accumulation of experience and mature PSP graphics core

In order to cooperate with the 3D function of PSP, Sony equipped PSP with the same number of GPUs as CPU. Graphics kernel 1 is mainly used for geometric operations.

3D Curved Suce 3D Polygon (supports 3D surface operation and 3D Polygon engine) Compression Texture compression (this is a very important technology, which can store more textures in limited memory and memory space, and texture compression can also reduce the utilization of main memory. Because when the memory is insufficient, that is, when the texture overflows, the system will store the texture in the main memory.

Texture compression can also effectively reduce bandwidth utilization. Since Sony did not specify the specific compression ratio, it is estimated that it is the texture compression technology of S3TC. Here, the texture compression ratio of S3TC is 2: 1 16BIT color, 4: 1 24BIT color, and 6: 1 hardware cropping (in short, cropping is to remove the part of the object that falls off the screen without dealing with the invisible things. Deformation and bone are deformation and bone animation respectively. They are very similar techniques, both of which make the movements of the characters smoother. Morphing enables developers to create real surfaces such as sea waves and water waves, or to change the triangle group from one shape to another, thus bringing smoother skeletal action effect [right 1 is an example of deformation]; Bone(8) enables programmers to use eight "bones" at each joint to create real character movements, and the joints will not deform during movement, which makes the character movements more real and natural. Hardware Tessellator is a hardware polygon subdivision function. Tessellator uses high-order surface geometry to make the original simple model of the game smoother and more detailed. After being added to the engine, we can use LOD technology (or high-order surface) in the program, and use 3D models with different wireframe densities according to the distance between the object and the observer. Due to the introduction of LOD, the number of polygons in the scene will be greatly reduced, but the picture quality will not be significantly reduced, and the hardware clipping work can also be improved because of the reduction of polygons. DX8.0 and OPENGL 1.4 are added. Only the NV2A hardware of X-BOX in the home game machine supports this function. However, this technology is not widely used in PC games. Although it is supported by hardware, it is invalid to turn on this computing function [such as ATI's TRUFORM] in PC games.

The graphics core 1 supports Bessel B-spline (NURBS * modeling function of Bessel curve), and 4× 4, 16× 16, 64× 64 are subdivided into subdivision modes (the greater the N*N, the smoother the curve surface), reducing programs/data and memory. Bus traffic (they are HZPER technology similar to ATI, which can be used to reduce bandwidth occupation. Without specifying their specific working modes).

PSP graphics core 1 looks more like a geometric operator. Personally, I feel that its function is closer to the vertex shader of PC graphics card [Note: What is a vertex shader? Vertex is the most basic element in computer graphics, and three vertices can be connected into a triangle to form a surface. In three-dimensional space, each vertex has its own data, such as coordinates (xyzw) and color values. Vertex shader is a series of instruction programs that manipulate vertex data in software layer, and it is the processing unit that executes these vertex shader programs in hardware, but its function may be slightly weak.

T& of graphics core 2 is an engine such as rendering engine, and its main functions are rendering and hardware T & ampl (hardware geometric transformation and illumination processing). This technology can make the surface of 3D model smoother, more accurate and more realistic without adding polygons, and handle the light source in real time, making the light source more realistic and producing the effect of reflected light source. In PS2, it is completed by VUO+VU 1 of EE. It also supports surface rendering. Graphics cores 1 and 2 are 128-bit cores, operating at 166MHZ, connected to its embedded 4M DRAM, and the data bus width is 256 bits.

The DRAM bandwidth is 5.3 GB/ sec. The pixel filling rate of Graphics core2 is 664 million per second, the number of texture maps per clock cycle is 4, the pixel pipeline is 4, and the working mode is 4* 1, that is, the TMU unit (texture mapping unit) of each pixel pipeline is 1. Many people think that the pixel filling rate of PSP will decrease when there are multiple textures, so don't worry. I didn't expect Graphics Core2 to support pixel shader (but I don't know the version) [Note: What is a pixel shader? After Vertex shader processing, it will be handed over to the setting engine to be converted into two-dimensional coordinate points on the screen (called fragments (called in OpenGL) or pixels (called in D3d)-that is, pixels). Pixels contain information similar to vertices, including color, depth coordinates and other data. Pixel shader is an instruction program for manipulating pixel data on the software layer. In hardware, it is the pixel unit that executes the pixel shader. Pixel shaders are mainly responsible for generating special effects and synthesizing textures, so there is no need for multiple TMU units to synthesize textures. At the same time, PSP makes the control of light source reach the pixel level, which enables PSP to better express physical special effects such as water and metal surface reflection.

Vertex shader and pixel shader are only supported by NV2A of X-BOX in home computers, and are widely supported in games, such as water in halo and metallic feeling of the armor of the protagonist commando. This is an advanced function that PS2 doesn't have. For example, the left side of Figure 2 shows Tu Tu. The maximum number of polygons in graphics kernel 2 is 33 m polygons per second (t&; It's half of the PS2. Although the performance is much worse than that of PS2, don't forget that the resolution of PSP is 480*272, and it is on a 4.5-inch screen, even though the number of polygons and the texture size are the original 1/3 _. They work together. The output is also the work of Graphics Core2, which outputs 24-bit color at most, and the output signal is RGBA, so the color reproduction is better. [Note: It is not excluded that Graphics Core 2 adopts the technology similar to NVIDIA Shading Rasterizer (NSR). NSR makes the real material properties reach the effect of per-pixelshading as much as possible, that is, the effect achieved by pixel shader processing pixel shading (but only close). NSR can dynamically shadow each pixel, which makes complex pictures rich in details. Functions such as pixel bump mapping can be used to achieve more exciting visual effects, such as bump mapping. NSR allows software developers to calculate lighting characteristics on a pixel-by-pixel basis in real time. In the past, when using illumination mapping or vertex illumination in graphics solutions, this method would lead to the loss of quality and accuracy in order to improve performance. When forced, users must choose between real-time rendering and full-function rendering. Developers don't have to rely on the basic multi-texture processing technology to deceive their eyes, because the function of pixel real-time shadow processing makes 3D elements look and behave very similar to their counterparts in real life. Therefore, when PSP has multiple textures, the pixel filling rate will not decrease. Using NSR, the wood grain looks more realistic, and the illuminated object not only emits faint light under strong light, but also shines real shadows, making the ripples and waves on the water surface more natural. The function of pixel lighting is not only more accurate and flexible than all lighting methods used in the past, but also will not reduce the real-time performance.

UMD

UMD is a multimedia storage medium specially developed by Sony for PSP- Universal Media CD. The maximum capacity can reach 1.79GB- 1.8GB, and the capacity does not exceed 1.8GB, but the diameter is only 6cm.. Moreover, due to the design of inserting UMD disk and disk cover into PSP to play games (refer to MD's practice), the possibility of UMD disk wear is greatly reduced.

UMD CD

At present, UMD discs are only in read-only format, using 128-bit AES encryption technology. All UMD discs are exclusively produced by Sony, and there is only one UMD disc production line in the world, with a value of 65,438+200 million. I believe that UMD D disk will not appear for a long time (at least ten years).

Specification: 60mm diameter optical disc, 660 nm laser diode, 1.8GB maximum capacity (double layer), 1 1Mbps transmission rate, AES encryption system, unique optical disc ID.

PSP GO canceled UMD optical drive.

memory stick

MS (memory stick): The memory card introduced by Sony in 1999 is commonly used in Sony series products, such as Sony notebooks and Sony digital cameras. It can store PSP game files, MPEG-4 movies (later new firmware supports MPEG-4 encoded by AVC) and MP3 music. There are 32mb5 12mb 1gb, 2gb, 4gb, 8gb 16gb and 32gb. At present, there is a high-speed version of the memory stick, that is, the high-speed version, with a purple appearance and the words high-speed under ms logo. At present, most high-speed memory chips in China are assembled (not original), but the quality of assembled memory chips is worrying because of the interest relationship.

M2 memory stick: It is a new memory card memory stick Micro(M2) jointly launched by Sony and Sandisk, which was launched in March 2006. The extended memory stick supported by PSPgo is M2 memory stick.

M2 memory stick

Similar to Mirco SD card, this M2 memory stick is designed with ultra-small circuit, which is specially designed for the requirements of large-capacity and small-volume mobile storage. Its weight is only 16g, its overall dimensions are15×12.5×1.2mm, and its volume is about a quarter of that of Ms. ..

M2 memory stick can be converted into ordinary memory stick (short stick) through M2 adapter, and used on Sony PSP 1000, PSP2000 and PSP3000.
