摘要
以高速数字信号处理器ADSP 21060和复杂可编程逻辑器件ACEX EP1K100构成的高速数字图像信号处理器为例,简要介绍了主机ACEX EP1K100与ADSP 21060的直接存储器访问(DMA)。调试结果表明,文中提出的设计方法可以让处理器内核从繁重的图像数据搬移工作中解脱出来,让数字信号处理器专心从事图像处理算法工作,显著地提高了系统的并行处理性能。
As the example of a high speed digital image signal processor in which ADSP 21060 and ACEX EP1K100 play the role of core device, the DMA between ACEX EPlk100 and ADSP 21060 is introduced briefly in this paper. This relieves the core processor of the burden of moving data, and obviously increases the parallel - processing ability of the system.
