Abstract
Though a deblocking filter of H.264/AVC provides enhanced image quality by removing blocking artifact on block boundary, the complex filtering operation on this process is a dominant factor of the whole decoding time. In this paper, we designed an ASIP to accelerate deblocking filter operation with the proposed instruction set. We designed a processor based on a MIPS structure with LISA, simulated a deblocking later model, and compared the execution time on the proposed instruction set. In addition, we generated HDL model of the processor through CoWare's Processor Designer and synthesized with TSMC 0.25um CMOS cell library by Synopsys Design Compiler. As the result of the synthesis, the area and delay time increased 7.5% and 3.2%, respectively. However, due to the proposed instruction set, total execution performance is improved by 18.18% on average.
