Abstract :
A parallel implementation of the two-dimensional, adaptive blocksize discrete cosine transform (DCT) is based on the principle of the quadtree structure. An efficient coding technique for the quadtree used is described. A network of Inmos T800 transputers is chosen as the target system. Two types of parallel network topologies are analyzed, and the results for execution time are presented. The results show that the tree structure is faster than the pipelining ring structure for this particular application
