Fast intra prediction mode decision using parallel processing

H.264 adapts rate distortion optimization (RDO) technique to get high coding rate and visual quality. Because RDO is too much exhaustive, several attempts have been made to explore fast algorithms. In all algorithms computational speed increased with a performance degradation. In the previous attempts only two variables were considered i.e. computational speed (CS) and performance (P). In this paper we also considered a third variable production cost (PC). In microelectronics devices, FPGA or ASIC, parallel processing enhances computation speed with the increase in production cost. In some cases when no compromise on performance, parallel processing is an effective tool to overcome computational complexity.
