Paper Abstract

Discrete Cosine Transformation (DCT) and Inverse Discrete Cosine Transformation (IDCT) are important parts of many image and video compression system. Unfortunately these operations are extremely computation-intensive in a coding system, it consumes a large amount of resources for computation, especially in a real-time video coding system. In this article an efficient method for hardware based DCT/IDCT implementation is proposed. We combine the vector processing with parallel processing using Distributed Arithmetic. At the same time the processing elements are pipelined to increase the processing speed and reduce the computation latency, which can also reduce the resource requirement and thus enhance the efficiency.
