- Abstract
- 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.
