최근에 2.5G나 3G 이동 단말 장치를 위한 프로세서로, 다양한 멀티미디어가 가미된 응용구현이 가능하도록 RISC 프로세서와 DSP를 포함하는 단일 칩 프로세서 기술이 등장하고 있다. 이에 따라 듀얼 프로세서 구조에서 비디오 인코딩/디코딩의 처리 속도를 향상시키기 위안 비디오의 인코더/디코더 구조를 제안한다. 기존의 연구에서는 비디오의 인코딩/디코딩의 전 과정을 DSP가 담당하도록 설계하였으나 많은 비트 연산이 필요한 부분에서는 RISC 칩보다 효율성이 낮게 된다. 이러한 문제점을 해결하기 위하여 본 논문에서는 비디오 신호 처리의 인코딩/디코딩을 구성하는 모듈들을 DSP와 RISC의 특성에 맞도록 분리해 수행시킴으로써 효율성을 높이고자 한다.
