摘要
一种基于高速数字信号处理器TMS320VC5410DSP和CPLD的图像采集、压缩系统,分析了系统设计时的各个关键技术环节,介绍了JPEG图像编码算法的DSP的实现,讨论了图像编码中DCT变换的实现和优化,利用DSP的乘法累加指令和双字加/减法指令快速实现DCT。
A hight-speed image data acquisition and compression system based on high-speed DSP TMS320VC5410 and CPLD is presented, and key problems of each unit are also analyzed. The realization of JPEG codnig based on DSP is introduced. Especially the realization and optimization of DCT transformation is discussed ,and it is realized fast with DSP multiplication-accumulation instructions and double-word additon/subtraction instuetions.
