基于DSP的多路串口扩展技术

Multi-Channel Serial Port Expansion Technology Based on DSP

DSP是一种高性能芯片,能够快速实现各种信号处理算法,在诸多领域得到大量的应用。在许多应用环境中,需要DSP处理多路串口数据,而DSP通常无法提供过多数量的串口资源,并且其内部的串口数据缓冲空间容量也无法满足实际需要,这种情况下就需要对其进行多路串口扩展。提出一种使用FPGA对其进行串口扩展的方法,克服了DSP在多通道数据传输方面的局限性,同时适用于多种串口协议,具有较强的灵活性和通用性。

DSP is a high-performance chip that can rapidly implement various signal processing algorithms and has been widely used in numerous fields.In many application environments,the DSP needs to process multiple serial port data,but it can hardly provide a sufficient number of serial port resources,or the internal serial data buffer space capacity cannot meet the actual needs.In this case,it is necessary to carry out multi-channel serial port expansion.A method for serial port expansion by using FPGA is proposed,which overcomes the limitations of DSP in multi-channel data transmission,and is applicable to a variety of serial port protocols,and has strong flexibility and versatility.
