Abstract:
A high energy efficiency processor applying DVS is provided to maximize energy efficiency represented as 'performance/total power consumption' by using a simple structure, support a parallel processing architecture by using a plurality of processors, and realize a parallel processor including the plurality of processing elements performing parallel processing. A function unit block(200) performs operation according to an instruction received from an instruction register(110). Each parallel unit block(400) communicates data with an external device. An instruction interpreter(120) interprets the received instruction, and determines an operation mode of the function and parallel unit block required for executing the interpreted instruction. A function unit block operator(300) applies a different voltage level from the operation mode of the function unit block. A parallel unit block operator(500) applies the different voltage level from the operation mode of the parallel unit block. The function unit block includes more than two function units and more than two function unit operators for applying the different voltage level by control of the instruction interpreter.

재구성형 SoC(System On a Chip) 구현시, 목적시스템 내부에서 재구성에만 사용되는 메모리의 공간을 없애고 이를 별도의 서버에 설치해 둔 뒤 재구성의 필요에 따라 구성용 데이터를 인터넷(유선 혹은 무선)을 통해 불러와 SoC의 내외부에 있는 메모리를 구성용으로 사용하게 하는 것을 그 특징으로 한다. 아울러 SoC 내외부의 메모리에 있는 데이터 중 재구성 후에도 보존되어야 할 데이터를 서버에 이전하여, 비워진 SoC 내외부의 메모리를 구성용 메모리로 사용 후 보존되어야 할 데이터를 복원시키는 방법을 제안한다.
