Highly energy-efficient processor employing dynamic voltage scaling

摘要

Provided is a highly energy-efficient processor architecture. The architecture employs 2-stage dynamic voltage scaling (DVS) and a sleep mode for high energy efficiency, dynamically controls the power supply voltage and activation of an embedded processor with instructions, and thus can prevent performance deterioration while reducing power consumption.;A highly energy-efficient processor employing the processor architecture includes: a function unit block for performing an operation according to instructions input from the outside; at least one peripheral unit block for performing data communication with an external device; an instruction decoder for interpreting the input instructions and determining operation modes of the function unit block and peripheral unit block required for executing the interpreted instructions; a function unit block driver for applying a different power supply voltage according to the operation mode of the function unit block to the function unit block; and a peripheral unit block driver for applying a different power supply voltage according to the operation mode of the peripheral unit block to the peripheral unit block.
