High-Speed Data Transmission System Design and Implementation Based on FPGA

Aimed at the non-standard Flash memory composed of 8 K9KAG08U0M Flash chips of Samsung Company, the paper introduces a high-speed data transfer interface with FPGA (Field Programmable Gate Array) as the main controller. With the synchronous DMA (Direct Memory Access) mode of USB2.0, the system implements the management, reading and transmission of the data in the memory. The design of the system proves in practice that the effective transmission speed reaches 30 MB/s and in just 15 minutes, all of the data in the 16.5 G bytes non-standard memory can be downloaded to the hard disk of the computer.
