Abstract :
This paper presents a multimedia processor based on a SIMD architecture optimized for block-based video processing algorithms. The processor, called DGP (digital generic processor), is a generic system architecture, constituted by an array of pixel processors (SIMD) and a RISC controller. It is able to execute various video processing algorithms such as digital filtering, video effects, window clipping, and to perform video compression according to standards such as H.261, H.263, MPEG-1 and MPEG-2. The processor can be programmed in order to run the code corresponding to each specific algorithm
