Abstract
An application processor for 3G cellular phones, using 0.18 /spl mu/m CMOS technology, includes a single CPU and DSP core with an on-chip 128 kB SRAM. It enables software-based 15 frames/s MPEG-4 encoding of QCIF Simple @L1 at 70 MHz and 140 mW. Standby current of the processor is <10 /spl mu/A in a partially powered standby mode using separate power lines.
