基于Solution Engine DMAC的多通道数据传输机制及应用

The Mechanism and Application of Multi-channel Data Transfer Based on Solution Engine DMAC

介绍了HI73180SolutionEngine直接内存访问控制器(DMAC)的特点,分析了其基本结构和工作原理,对相关寄存器的配置进行了详细阐述,并在此基础上实现了基于DMAC多通道数据高速传输方法的AVS-M纯软件解码。

The structure and working principle of HI73180 Solution Engine＇s direct memory access controller（DMAC） was analyzed in this paper. By using the DMAC to perform multi-channel high-speed data transfer, a pure software AVS-M decoder was implemented.
