The PSP (short for PlayStation Portable) is a handheld game console released and currently manufactured by Sony Computer Entertainment. Its development was first announced during E3 2003, and it was officially unveiled on May 11, 2004 at a Sony press conference before E3 2004. The system was released in Japan on December 12, 2004, the United States and Canada on March 24, 2005 and in Europe and Australia on September 1, 2005. It is considered the first handheld video game system to use an optical disc format (Universal Media Disc).
A new slimmer and lighter version of the PSP, appropriately titled Slim and Lite, was announced on July 11, 2007, during Sony's press conference at E3 2007. It was made available in the US, Europe and Japan in September 2007 with various colours and a very different box packaging to the original PSP. Among these versions three were physically shown at E3 2007: a white version with a Star Wars imprint, a piano black version and an ice silver version.
The PSP was designed by Shin'ichi Ogasawara (小笠原伸一) for the Sony Computer Entertainment subsidiary of Sony Corporation. Early models were made in Japan but in order to cut costs, Sony has farmed out PSP production to non-Japanese manufacturers, mainly in China.
The unit measures 170 mm (6.7 inches) in length, 74 mm (2.9 inches) in width, and 23 mm (0.9 inches) in depth, and has a mass of 280 grams (a weight of 0.62 lb) including the battery. The Samsung (previously Sharp) branded TFT LCD screen measures 110 mm (4.3 in) diagonal with a 16:9 ratio and a 480×272 pixel resolution capable of 16.77 million colors. It has four possible brightness settings, the brightest of which is disabled in the older firmware versions unless on A/C power.
The PSP's main microprocessor is a multifunction device named "Allegrex" that includes a 32-bit MIPS32 R4k-based CPU, a Floating Point Unit, and a Vector Floating Point Unit. Additionally, there is a processor block known as "Media Engine" that contains another 32-bit MIPS32 R4k-base CPU, hardware for multimedia decoding (such as H.264), and a programmable DSP dubbed "Virtual Mobile Engine". The secondary CPU present in the Media Engine is functionally equivalent to the primary CPU save for a lack of a VPU. The MIPS CPU cores are globally clocked between 1 and 333 MHz. During the 2005 GDC, Sony revealed that it had capped the PSP's CPU clock speed at 222 MHz for licensed software. Its reasons for doing so are unknown, but are the subject of some speculation. Various homebrew tools enable users to operate at 333 MHz, generally leading to a higher frame rate at the expense of battery life. On June 22, 2007, Sony Computer Entertainment confirmed that the firmware version 3.50 does in fact remove this restriction and allows future games to run at the full 333 MHz speed. It does not affect already-released games.
The system has 32 MiB main RAM and 4 MiB embedded DRAM. The 4 MiB of eDRAM consists of 2MiB dedicated to the Graphics Unit and 2MB dedicated to the Media Engine secondary processor. There is no memory management unit for either CPU. No evidence of a TLB has been found. The co processor that normally manages the TLB-based MMU seems to be a custom effort by Sony and has no integrated memory. Both CPUs contain 16KiB of two-way set associative instruction cache and data cache respectively. There is additionally 16KiB of scratchpad RAM which, while faster than main RAM, is not nearly as fast as the integrated cache.
The 166 MHz graphics chip has 2 MiB embedded memory and through its 512 bit interface provides hardware polygon and NURBS rendering, hardware directional lighting, clipping, environment projection and texture mapping, texture compression and tessellation, fogging, alpha blending, depth and stencil tests, vertex blending for morphing effects, and dithering, all in 16 or 24 bit color. The graphics chip also handles image output. Specifications state that the PSP is capable of rendering 33 million flat-shaded polygons per second, with a 664 million pixel per second fill rate.
