| Abstract: | A high-speed data transmission system is designed and implemented using FPGA as the main control unit, EZ-USB FX2 microprocessor as the interface chip. This paper presents the design scheme of the hardware and software for data transmission between FPGA and CY7C68013, emphatically introduces the FIFO principle internally integrated in FPGA and the program implementation method. By designing the handshake process between FX2 and FLASH, we realize the high-speed data transmission between the data memory and PC. This data transmission system is reliable, effective and universal, can be used in other systems which use USB carrying out data transmission. |
