Abstract

A 104.8mm2 90nm CMOS 600MHz SoC integrates 8 processor cores and 8 user RAMs in 17 separate power domains and delivers 33.6GFLOPS. An automatic parallelizing compiler assigns tasks to each CPU and controls its power mode including power supply in accordance with its processing load and status. The compiler also uses barrier registers to achieve fast and accurate CPU synchronization.
