And BTW, its not exactly a MIPS processor. Read the article, its an in house Toshiba Processor, along with 1, maybe 2 coprocessors. Maybe the coprocessor offloads graphics duties from the CPU, which could make it the fastest PPC. MIPS doesnt make a 129mhz processor.
"Firstly, the MPU (Main Processor Unit) that will be used in the Toshiba PPC is likely to be the TMPR3922CU, developed specifically for Windows CE devices by Toshiba itself. It's a MIPS-based 32-bit CPU, capable of processor speeds of up to 129 MHz. Secondly, the companion chip for the TMPR3922CU is the TC6358TB, which is capable of controlling a TFT display, PCMCIA and Smart Media as well as USB and other Input/Output functions."
