Abstract
최근 모바일 멀티미디어 기기들의 사용이 증가 하면서 고성능 멀티미디어 프로세서에 대한 필요성이 증가하고 있다. 본 논문에서는 낮은 소비전력으로 고성능 멀티미디어 애플리케이션을 구현할 수 있는 SIMD기반 병렬프로세서를 제안한다. 제안하는 병렬프로세서는 16개의 프로세싱 엘리먼트로 구성되어 있으며, 3단계 파이프라인 구조로 설계되었다. 모의실험 결과, 제안한 SIMD기반 병렬프로세서는 기존의 병렬프로세서보다 프로세싱 엘리먼트 당 상대 연산 처리량에서 높은 성능을 보였으며, 또한 동일한 130nm 테크놀리지와 720 클록주파수에서 상용 고성능 프로세서인 TI C6416보다 1.4~31.4배의 성능 향상 및 5.9~8.1배의 에너지 효율 향상을 보였다. 제안한 병렬프로세서를 하드웨어 설계언어인 verilog HDL을 이용하여 설계하였고, FPGA를 이용해 검증하였다. As the use of mobile multimedia devices is increasing in the recent year, the needs for high-performance multimedia processors are increasing. In this regard, we propose a SIMD (Single Instruction Multiple Data) based parallel processor that supports high-performance multimedia applications with low energy consumption. The proposed parallel processor consists of 16 processing elements (PEs) and operates on a 3-stage pipelining. Experimental results indicated that the proposed parallel processor outperforms conventional parallel processors in terms of performance. In addition, our proposed parallel processor outperforms commercial high-performance TI C6416 DSP in terms of performance (1.4-31.4x better) and energy efficiency (5.9-8.1x better) with same 130nm technology and 720 clock frequency. The proposed parallel processor was developed with verilog HDL and verified with a FPGA prototype system.
