Abstract: By the use of PCI Express interface, and parallelization and pipelining technology, the rate of read and write is raised. A reasonable Flash Translation Layer(FTL) algorithm is designed, the great convenience data management without reducing read and write performance is supplied. The design is implemented on the Virtex 5 FPGA, and its performance is tested. The consecutive write rate is about 400 MB/s, and read rate is up to 500 MB/s. This can meet the demand for high level application.
