Abstract

In this paper, the hardware(HW) and software(SW) co-design methodology of H.264/AVC decoder using ARM-Excalibur is proposed. The SoC consists of embedded processor, memory, peripheral device and logic circuits. Recently, the co-design method which designs simultaneously HW and SW part is a new paradigm in SoC design. Because the optimization for partitioning the SoC system is very difficult, the verification must be performed earlier in design flow. We designed the H.264 and AVC Decoder using co-design method. It is shown that, for the proposed co-design method, the performance improvements can be obtained.

본 논문에서는 H.264 및 AVC 디코더를 ARM-Excalibur를 이용하여 하드웨어(HW:Hardware)와 소프트웨어 (SW:Software)로 병행설계(co-design)하는 방법에 대해서 제안한다. 내장형 프로세서, 메모리, 주변장치 및 논리 회로들을 하나의 칩으로 집적한 SoC(System On-a-Chip)를 하드웨어와 소프트웨어로 분할하여 병행 설계(co-design)하는 방식이 새로운 설계 방법으로 대두되고 있다. 최적화된 분할 방법을 찾는 것이 매우 어렵기 때문에 설계 초기단계에서 빠르게 검증할 필요가 있는데 본 논문에서는 H.264 및 AVC 디코더를 알테라사의 ARM-Excalibur라는 칩을 이용하여 효율적으로 병행 설계하였으며 시스템의 동작속도가 크게 향상되는 것을 확인할 수 있었다.
