基于JPEG图像解码的高速Huffman解码电路
A High Speed Huffman Decoding Circuit Based on JPEG Images
【摘要】 研究JPEG图像的Huffman解码器在集成电路上的实现问题,以范式Huffman编码为研究对象,在研究范式Huffman编码特点及快速算法的基础上设计出高速Huffman解码电路。此解码电路已经在Altera的FPGA上通过测试,系统能稳定运行在140 MHz,输出数据平均达到约1.2 Gb/s的带宽。
【Abstract】 This paper presents a circuit of high speed Huffman decoding for JPEG images by studying the Canonical Huffman code and fast algorithm of decoding.It takes much smaller memory in size and the decoding becomes signicant faster.The design has been implemented on FPGA(Altera APEX20KE1500EB652) and it can run stably at the speed of 140 MHz wit high output bandwidth(about 1.2Gbits/sec average).
