| Abstract: |
The in-loop deblocking filter contains highly adaptive processing on both sample level and block edge level, which inevitably appears in the loop kernel of the algorithm. Therefore it is a challenge for parallel processing on a digital signal processor (DSP) platform. In this paper, pipelined DSP solutions to the in-loop deblocking filter in AVS1-P2 are presented. First, the whole filter process is divided into six sub-processes, so that the global filter structure can be improved to achieve regular processing flow. Then software pipelines are designed for these sub-processes, with elaborately allocating functional units and carefully choosing enhanced assembly instructions based on the DSP platform. The simulated results show that this efficient implementation can easily support real-time filter processing for high resolution videos. |
