subject: Sony Psp Hardware [print this page] . The Sony PSP is a flat, candybar device that measures roughly 6.7x2.9x0.9 inches and weighs just under 300 grams.
The most striking feature, without a doubt, is the large 4.3 inch LCD screen that displays 16 million colors at a resolution of 480x272 pixel. On the right of the screen are the four standard buttons found on the DualShock and SixAxis - Cross, Square, Triangle and Circle.
On the other side of the screen, users will find a four-way navigational pad for movement as well as an analogue 'nub' below it.
Below the screen, a row of buttons provide options such as the PlayStation Home button, increasing and decreasing volume, 'Select', 'Start', music settings and screen settings.
The corners at the top of the PSP feature two translucent 'bumper' buttons, which imitate the functions of the L1 and R1 buttons on the DualShock.
Processor and GPU - The main microprocessor of the PlayStation Portable is a multifunctional device named 'Allegrex' that pump two 333 MHz R4000-based CPUs. The hardware was originally forced to run more slowly than it was capable and most game ran at 222 MHz. However, with firmware upgrade 3.50 on 31 May 2007, Sony removed this limit and allowed the games to run at a full 333 MHz.
The Sony PSP relies on tiny Graphics Processing Unit. The whole system has 32 MB main RAM in the original Sony PSP and 64 MB im the PSP 2000 and subsequent series, and 4 MB embedded DRAM im all models. Out of these 4 MB of eDRAM, 2 MB is dedicated to the GPU and 2 MB is further dedicated to the Media Engine Secondary Processor.
