Yesterday, Sony revealed some details about the chips they will be using to power their upcoming Playstation Portable. The chipset includes the CPU, a 3D graphics engine, a media processor, a security processor and a power manager. The MIPS R4000-based CPU runs at 333MHz, its frontside bus runs at up to 166MHz, with both frequencies controlled by processor load and it contains a vector processing engine according to Sony chip designer Masanobu Okabe. The graphics sub-system will operate across a 512-bit bus and is capable of rendering 664m pixels per second and 35m polygons per second. The core operates at 166MHz and includes 2MB of integrated buffer DRAM and a further 2MB of embedded DRAM is dedicated to the main processor.
The dedicated security engine will be used in attempt to prevent game piracy and protect the PSP from being hacked. Sony's other gaming consoles have all been hacked and modchips are used to bypass the security. Sony hopes this new technology will eliminate piracy of PSP games.
The PSP will support USB 2.0, MemoryStick and up to 32MB of DDR SDRAM. The PSP will feature a 4.3in, 480 x 272 widescreen LCD and will weigh 260g. It measures 17 x 7.4 x 2.3cm. It uses a 1.8GB optical disc called Universal Media Disc to store content.
