2-D DCT systolic array implementation
Weihong Ma · Electronics Letters · 1991
The algorithm and architecture of a 2-D systolic array processor for the DCT (discrete cosine transform) are proposed. It is based on the relationship between DCT and cosine DFT and sine DFT. Two systolic architectures of 1-D DCT data and control flow computation are discussed. By use of the main feature of the two systolic 1-D arrays for DCT, a full 2-D systolic DCT array is presented.
