TMS320C3x高速数据采集的DMA实现

High Speed Data Acquisition Implemented with DMA of TMS320C3x

介绍了通用数字信号处理器 TMS32 0 C3x的 DMA结构及其应用设计 ,分析了采用 C3xDMA进行高速实时数据采集的硬件和软件设计要点 ,成功实现了 DMA高速数据采集和数据运算的并行处理 ,使系统具有较高的集成度和性价比。

Introduces a structure of DMA on TI′s general digital signal processor C3x and its application design. The key of hardware and software design on high speed data acquisition for DMA is analysed. This paper designs a high speed data acquisition circuit of a multi processor signal processing system by using DMA of C3x. By the cooperating of system hardware and software, high speed data acquisition and data processing can be parallel. It makes the system has high integration and performance but low cost.
