A 0.9V to 1.95V Dynamic Voltage-Scalable and Frequency-Scalable 32b PowerPC Processor Academic Article uri icon


  • A 32 b PowerPC™ 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 μm CMOS process. Maximum supply change without PLL relock is 10 mV/μs. Processor state save/restore enables a deep-sleep state.
