Design of Bus Protocol Conversion Board Based on FPGA+ARM for Large Scientific Installations

In large scientific installations, there are various intelligent monitoring and control terminals, each using a different bus communication protocol. This project involves the system development of an embedded universal middleware based on ARM and FPGA. The system mainly includes a core bus module, a USB communication module and a signal relay module. It is connected to the host computer through USB and communicates with various smart devices at the other end. The system allows the host to freely select the desired bus communication protocol, thus realizing the communication with various intelligent devices. Simulations and tests show that the system can accurately and losslessly transmit various data and meet the requirements of large scientific installations.
