英文摘要 | In this paper, we propose an optimized realtime a vs (a chinese next-generation audio/video coding standard) hdtv video decoder. the decoder has been implemented in a single soc with hw/sw partitioning. avs algorithms and complexity are first analyzed. based on the analysis, a hardware implementation of the mb level 7-stage pipeline is selected. the software tasks are realized with a 32-bit risc processor. we further propose the optimization of interface and risc processor based on the proposed architecture. the avs decoder (risc processor and hardware accelerators) is described in high-level verilog/vhdl hardware description language and implemented in a single-chip a vs hdtv real-time decoder. at 148.5mhz working frequency, the decoder chip can support real-time decoding of ntsc, pal or hdtv (720p@60 frames/s or 1080i@60 fields/s) bit-streams. finally, the decoder has been fully tested on a prototyping board.(1) |
