본 논문에서는 Parsec을 이용하여 병렬디지털신호처리용 분산공유메모리 다중처리시스템의 성능 분석을 위한 시뮬레이터를 구현한다. 이 시뮬레이터의 특징은 TMS320C6701 DSP 칩의 DMA 기능과 빠른 접근시간을 가진 지역메모리를 사용하는 시스템의 시뮬레이션에 적합하다는 것이다. 또한 시스템의 성능 매개변수 수정과 하드웨어 구성요소들에 대한 재구성이 쉽기 때문에 다양한 실행 환경에서 시스템의 성능을 분석할 수 있다. 시뮬레이션에서는 DSP 알고리즘에서 널리 사용하는 FFT, 2D FFT, Matrix Multiplication, Fir Filter를 사용하여 프로세서의 수, 데이터 크기, 하드웨어 요소의 변화에 따른 실행시간을 측정한다. 그리고 그 결과를 비교함으로써 본 논문에서 구현한 시뮬레이터의 성능을 검증한다.
