The interface design and realization of EMIF and FPGA for wireless transmission of image data

Abstract

In order to meet the requirements of wireless image transmission system, an interface was designed for external memory interface(EMIF) of TMS320DM365 and FPGA. Firstly, their hardware connection was given, and a stable pin is used as interrupt signal. Then the EMIF device driver under embedded Linux system was described in detail. The working process in both transmission and receiving FPGA were introduced. In order to match the communication between FPGA and DM365, the FPGA was adjusted to make the connection with DM365 seamlessly. Finally, through the circle test of sending data between DM365 and FPGA, correctness and stability of the design of the interface were verified.
