AN ASIP Approach for H.264/AVC Implementation Having Novel Coprocessors
We present an ASIP (application-specific instruction-set processor) approach for H.264 implementation having novel coprocessors. We have previously proposed the video specific instruction-set processor (VSIP) for H.264/AVC. To improve performance of motion estimation (ME) further, we propose a new improved ME accelerator using the modified normalized partial distortion search (MNPDS) algorithm. The proposed MNPDS can reduce the average computational complexity by 96.2-99.5% compared to the full search algorithm whereas the PSNR decreases only 0.04 dB. Hence, VSIP using MNPDS is one of promising candidates for real-time video processing.
