摘要
介绍一种使用高性能通用DSP实现时隙交换电路的设计方法。介绍了TMS320VC5410的主要特点,详细描述了使用DSP设计时隙交换电路的工作原理,DSP系统的内存地址分配,多通道串口McBSP和DMA的硬件功能配置,DSP软件系统设计处理流程图。通过DSP系统的性能分析和交换机实际运行结果,表明该设计方法高效可行,可以保证很好的交换速度和质量。
In this paper, we introduce a design method that is an implementation of time slot switching circuit based on high performance general DSP- TMS320VC5430, describe the main character of TMS320VC5410 and illustrate the operation principles of time slot switching with DSP and DMA address distribution in DSP system. The function configuration of Multicharmel Buffered Serial Port and DMA and the software design flow of DSP system are described in detail. The practical application results show that this method is efficient and feasible, the speed and quality are guaranteed for sure.
