Abstract—A microprocessor system is presented in which the supply voltage and clock frequency can be dynamically varied so that the system can deliver
high throughput
when required while significantly extending battery life during the low speed periods. The system consists of a dcdc switching regulator, an ARM V4 microprocessor with a 16kB cache, a bank of 64kB SRAM ICs, and an I/O interface IC. The four custom chips were fabricated in a standard 0.6 m 3metal CMOS process. The system can dynamically vary the supply voltage from 1.2 to 3.8 V in less than 70 s. This provides a throughput range of 6‐85 MIPS with an
energy consumption
of 0.54‐5.6 mW/MIP yielding an effective energy efficiency as high as 26 200 MIPS/W. Index Terms—Adaptive processor, energy efficient, low power,
