摘要
提出了一种新的基于DCT的JPEG图像压缩软件实现技术,该技术有效地利用了RISC架构和量化DCT域表示的数据。因此,使用32位RISC CPU和DRAM,可以在大约0.5秒内编码和处理4:2:2格式的640 x 480 (VGA大小)YCbCr图像。
JPEG Software Implementation Techniques Based On A 32-bit RISC CPU
New implementation techniques of DCT-based JPEG image compression software is proposed The techniques make effective use of RISC architecture and data of the quantized DCT domain representation. As a result, 640 x 480 (VGA size) YCbCr images in the 4:2:2 format can be encoded and &co&d in about 0.5 seconds by using a 32-bit RISC CPU and DRAM.
