摘要
DSP(digital signal processing)因其强大的数据处理能力,在通讯、图像处理、雷达等领域应用越来越广泛。要使DSP充分发挥其强大数据处理能力,外部的数据接口设计便显的极为重要。本文通过实践,在一个双TMS320C6416的系统中,设计了一种利用EDMA(Enhanced Direct Memory Access)+MCBSP(Multichannel Buffered Serial Port)的高速数据传输接口,在CCS3.1集成开发环境下,利用BIOS(base input/output system)工具,实现了两个DSP系统之间的高速数据传输,并成功运用到产品当中,运行良好。
DSP (digital signal processing) has been applied into the communication , picture processing, radar and so on ,because of its strong data-handling capacity. If we want to make full use of the strong capacity of processing , we must know that the design of the external data- transmission interface is extremely important, through practice, one kind of high speed data- transmission interface is designed ,based a double TMS320C6416 system, using the EDMA (Enhanced DirectMemory Access) and MCBSP (Muhichannel Buffered Serial Port) . The tool of BIOS (base input/output system) is also used under the CCS3.1 integrated development environment. At last , two DSP high-speed data- transmission has been realized and has been used to the product successfully .
