| Abstract: | Based on the AVS video standard,Exp-Golomb algorithm is analyzed first.And then we propose a hardware architecture of VLD module,whose decoding control is realized by customized instructions.Finally,the decoder is described in RTL Verilog HDL and verified with the C-model constructed by the rm52j standard code.The experimental results show that the proposed VLD module satisfies the requirements of entropy decoder of AVS standard. |
