Design of micro data memory system based on FPGA

The design of micro data memory system based on FPGA is detailed in the paper.FPGA controls the reading,writing and erasing operation of Flash,the data in which is transported to upper computer by USB interface to realize data reading and display.The system adopts FPGA as the main controller of Flash.The data size of the transmission is 8 bit(1 byte)or more.The communication of USB interface is based on CY7C68013,the control logic of which is realized by FPGA.The system design realizes convenient program compiling with high speed and high capability Flash,and USB interface has many advantages such as high speed transmission,supply hot swap,low cost,wide application.
