Research On Communication Technology Of Embedded VPX Signal Processing System

The signal processing system has extensive applications in the field of image processing,communication and military.Signal processing device of FPGA has the characteristics of low power consumption and high efficiency.Using FPGA,DSP,and MCU collaborative processing architecture can give full play to their advantages,which has a broad application value.In this paper,we studied in depth with the communication of the signal processing system.On the basis of hardware design,we used software to realize the debugging of communication routes and the basic function.The paper first designed the health management module,detected the state of the system by using BIT technology and provided a solution for the failure.Then,we designed the reconfiguration data transmission routes based on SRIO communication network,reconfigured MCU and FPGA by reconfiguration control route.After that,we designed a driver for communication between FPGA and WINMOWS system,realized the real time storage of signal processing data.Finally,we built a software and hardware environment for testing and validation,simulated data transmission routes,test the various data routes of the signal processing system.Through this paper,we made different part in signal processing system connect each other,made sure that the system work in a correct status,and laied the foundation of the following study on algorithm.After experimental verification,the signal processing system was in normal working state.it monitored the working state of the system in real-time,realized the function of dynamic reconfiguration,realize the transmission of PCIe data.
