Realization of high speed mass storage Data Record Card with CF Card and SDRAM

This paper presents a design that realizes a dual-channel Data Record Card which achieves 33 MB/s data transfer rate and 4 GB capacity per channel with CF Card and SDRAM. According to the characteristics of data transfer with CF Card, an advanced data transfer method is provided, which reduces the requirements of memory resources in FPGA without influencing the data transfer rate. And it realizes high speed data transfer between CF Card and low-end FPGA with limited memory resources.
