摘要:
以LSI Logic公司的双核嵌入式处理芯片ZEVIO 1020为核心,构建了一个高性能的JPEG解压缩处理系统,并根据处理器中ARM9和ZSP400的配合调用机制.该系统从SD卡中获取压缩数据,经过熵编码、反量化、IDCT变换等步骤,实现了JPEG压缩数据的快速解码.实验结果表明,所设计和实现的解码系统具有高性能、高效率、低成本的特点.
Abstract:
This paper proposed a JPEG decompression algorithm, in which the double core chip ZEVIO 1020 of LSI Logic Company was used. It adopted coordination transformation mechanism of ARM9 and ZSP400. The system acquires compressed data from SD card, and achieves fast decoding of JPEG compressed data by entropy encoding, inverse quantization and IDCT, etc. Experiments show that the designed decoding system has the characteristics of high performance, high efficiency and low cost.
