摘要 实现了静态图像压缩标准-JPEG算法在TMS320C6711DSP上的移植,采用了软件流水,内联函数等代码优化措施,实现了基本的数据压缩。使用了DSP外设接口HPI与PC机进行数据交换,在保证图像质量的前提下,获得了较高的压缩比。 The JPEG algorithm is transplanted to TMS320C6711DSP.The basic data compression algorithm is realized due to specific optimization measures such as pipeline,inline function.HPI interface is used as data transmission in the system.High compression ratio is obtained from experiments on the basis of ensuring image quality.
