A 32 b PowerPC/spl trade/ system-on-a-chip supporting dynamic voltage supply and dynamic frequency scaling operates from 366 MHz at 1.8 V and 600 mW down to 150 MHz at 1.0 V and 53 mW in a 0.18 /spl mu/m CMOS process. Maximum supply change without PLL relock is 10 mV//spl mu/s. Processor state save/restore enables a deep-sleep state.
