The Register reports: Sony has offered more detailed specifications for its upcoming handheld PlayStation console, the PSP.
Most notably, the new machine will feature built-in 802.11 wireless networking to enable multi-player gaming, the company said in Japan yesterday.
The PSP will be powered by a 90nm processor built from a MIPS 32-bit R4000 cores. The chip will feature a SIMD vector processing engine along the lines of Intel’s SSE and PowerPC’s AltiVec. Together with the chip’s floating point units, the vector engine can churn out 2.6GFlops, Sony said.
It will feature 8MB of embedded memory clocked to 333MHz and operating at 1.2V. The memory bandwidth is quoted as 2.6GBps.
A second MIPS R4000 core will be used as the basis for the PSP’s media engine, with 2MB of embedded DRAM, and again fabbed at 90nm.
Alongside these two chips will sit two dedicated graphics processors, one for high-level graphics manipulation , handling surfaces, bones, b-splines (nurbs), bezier curves and the like, and the other for the raw pixel shunting. This second core contains 2MB of embedded video memory operating across a 256-bit 5.3GBps bus. It can deliver a fill rate of 664 million pixels per second in 24-bit colour and churn out 33 million polygons per second with transform and lighting effects.
