Abstract :
A triple-CPU mobile application processor is developed on an 8.95mm×8.95mm die in a 0.13μm CMOS process. The IC integrates 3×ARM926 cores, a DSP several accelerators, as well as strong bus and memory interfaces. It consumes 120mW for digital TV, Web browser, and 30 graphics, and 250mW@200MHz for 600MIPS with full processing.
