Central processing unit: original Sony “Allegrex” multipurpose CPU based on 1/333 MHz configurable speed, includes a 32-bit MIPS32 Rk-4 based CPU, an FPU (Floating Comma Unit) and a calculation VFPU vector. It also includes a processor known as “Media Engine”; being also a CPU based on MIPS32 Rk-4 of 32 bits dedicated to the handling of audio / video by hardware and a DSP (Digital Signal Processor) programmable “Virtual Mobile Engine”. The “Media Engine” has similar functionality to the main CPU and serves as an equivalent in the absence of VPU.
Memory: 32 MB RAM of main memory (64 MiB in PSP Slim & Lite and following) and 4 MiB DRAM embedded; the 4 MiB correspond to 2 MiB for the graphics chip and 2 MiB of the “Media Engine”, both CPUs contain 16KB of instruction cache and data cache and 16KB of scratchpad, in addition to 32 MiB of NAND Flash memory, used to save configurations and system files.
Graphic processor: Original GPU speed configurable in 1/166 MHz with 2 MiB of internal memory and 512-bit interface supporting rendering of polygons and NURBS, directional lighting by hardware, environment projection and texture mapping, compression of textures and mosaics, fog, alpha blending, depth and stencil test, vertex blending for morphing and dithering effects; all in 16 or 24 bits of color depth. The graphics chip also handles video output. The system is capable of moving about 33 million illuminated and treated polygons, with a rate of 664 thousand pixels per second.
Parts of the PSP
Sound chip: Custom DSP configurable Sony “Virtual Mobile Engine” 3D Sound, Multi-Channel 7.1ch. The sound quality is far superior to that of other portable consoles.
Display: 4.3 inches, 16: 9 widescreen TFT LCD 480 x 272 pixels (16.77 million colors).
Battery: lithium smart with a lifespan of 2 years if it is charged correctly and is not used 100% of the time. It recharges in 3 or 4 hours approximately if it is second-hand, or 2 hours and 20 mins approximately if it is new. Duration in game from 3 to 6 hours, in video playback from 3 to 5 hours. It is convenient to buy a replacement battery for later use, as there are several models. The battery of the psp 1000, which tends to disappear, being thicker does not fit the other models and conversely, the others are too baggy. Capacity 5V DC 1800mAh, in the PSP 1000 and 5v DC 1200mAh in the remaining ones. In PSP GO the battery is not removable. There are expansion kits up to 2200mAh that protrude enough from the niche and use a special cover.
Codecs: ATRAC3 plus, AAC, MP3, WMA, AVC / @ MP for Picture / Movi, H.264 (MPEG-4 Part 10). Support images in JPEG, GIF, TIFF, BMP and PNG format.
Media: reading data from the UMD (Universal Media Disc) and Memory Stick optical disc system, remote connection and operation of the PlayStation 3 system. TV output on PSP Slim & Lite.
Wi-Fi: Wi-Fi IEEE 802.11b allows Ad-HOC and Infrastructure connection with other PSPs and with Internet with playability for 2/16 players simultaneously. The system software includes a Web Browser based on Access NetFront.
Gamesharing: some PSP system titles support game transfer in multiplayer mode with other consoles that do not have the game in question; This is achieved by sending the data through an Ad-Hoc connection and loading it onto the RAM. Support for this option is limited to games that make use of it.
Accessories: “Chotto Shot” 1.3-megapixel video camera with microphone, GPS signal receiver, digital TV receiver and PSP Headset, included with certain titles. The headphones have remote control capability.
Interface: XMB “XrossMediaBar” developed by Sony and present in its new TVs as well as in the PlayStation 3 system.
Measurements: 190 mm wide, 110 TFT screen, and 74 mm high.
Weight: 260 g without battery, 330 grams with battery (PSP 1000) The 2000 weighs 189g.
Design: Shin’ichi Ogasawara for Sony Computer Entertainment, a subsidiary of Sony Corporation.
