본 논문에서는 적은 메모리 공간을 가진 이동 단말 장치와 같은 임베디드 시스템에서 많은 메모리를 필요로 하는 비디오 디지털 신호처리 알고리즘이 동작될 수 있도록 움직임 검출을 효율적으로 구현하는 방법을 제시한다. 즉, 움직임 검출 알고리즘을 구현할 때 현재의 매크로 블록과 다음의 매크로 블록간의 참조 탐색 영역의 중복성이 존재함을 인지하여, 필요 메모리의 데이터 이동을 최소화시켜 내부 메모리를 효율적으로 이용하려 한다. 이렇게 움직임 검출에서 적은 내부 메모리를 이용함으로써 내부 메모리를 다른 용도로 사용할 수 있는 가용성을 증대시키고, 내부 메모리에서 보다 많은 연산을 수행하게 함으로써 빠른 성능으로 복잡한 MPEG-4 비디오 부호화 알고리즘의 구현이 가능하도록 한다.
