PSPのCPU

PSP - LinuxMIPS
Some basic specs of the PSP:

* two MIPS32R2 cores with no TLB
* 128bit Bus
* 1 - 333MHz @ 1.2V (currently capped at 222MHz (The 222MHZ cap is software based and lies in the executed files, it is not firmware based so is easily bypassed))
* Main Memory: 32MB, 4MB eDRAM
* Bus Bandwidth: 2.6GB/sec
* I-Cache, D-Cache
* FPU, VFPU (Vector Unit) @ 2.6GFlops
* 3D-CG Extended Instructions

安価なマルチコアMIPSプロセッサが乗っているというので一瞬（BSDを入れて遊ぶ為に）買っちまおうかとか思ったのだが、MMUがないのねん。しょぼん。
