Multi-channel low-speed port and single-channel high-speed port data interaction method

A multi-channel low-speed port and single-channel high-speed port data interaction method comprises the steps that an FPGA collects data of a multi-channel interface and sends the collected data to aDSP through an internal high-speed serial port; the DSP receives the data sent by the FPGA, analyzes and operates the data, and returns the analyzed and operated data to the FPGA; and the FPGA sends the data returned by the DSP to a multi-channel interface. According to the technical scheme provided by the invention, the internal data communication can be accurately and efficiently realized, and the system compatibility is stronger, and the FPGA is prevented from being repeatedly modified, and the development and debugging period is shortened. 一种多通道低速口与单通道高速口数据交互方法，包括：FPGA采集多通道接口的数据，并将采集的数据通过内部高速串口发送至DSP；所述DSP接受所述FPGA发送的数据并对数据进行分析和运算，并将分析和运算后的数据返回至所述FPGA；所述FPGA将所述DSP返回的数据发送至多通道接口。本发明提供的技术方案不仅可以准确高效的实现内部数据通讯，还使得系统兼容性更强，避免FPGA重复修改，缩短开发调试周期。
