A resume-standby application processor for 3G cellular phones

Abstract

A 389MIPS application processor for 3G cellular phones is implemented in a 0.13/spl mu/m dual-V, process. This dual-issue superscalar CPU with DSP runs at 216MHz at 1.2V and provides a resume-standby mode with a quick recovery feature using data retention of memory. The leakage current is estimated to be 98/spl mu/A when the power supply is internally cut off.
