In domains of aerospace, aviation, aiming, and optic measure etc., the embedded system of imaging, processing and
recording is absolutely necessary, which has small volume, high processing speed and high resolution. But the embedded
storage technology becomes system bottleneck because of developing slowly. It is used to use RAID to promote storage
speed, but it is unsuitable for the embedded system because of its big volume. Fiber channel (FC) technology offers a
new method to develop the high-speed, portable storage system. In order to make storage subsystem meet the needs of
high storage rate, make use of powerful Virtex-4 FPGA and high speed fiber channel, advance a project of embedded
system of digital image storage based on Xilinx Fiber Channel Arbitrated Loop LogiCORE. This project utilizes Virtex-
4 RocketIO MGT transceivers to transmit the data serially, and connects many Fiber Channel hard drivers by using of
Arbitrated Loop optionally. It can achieve 400MBps storage rate, breaks through the bottleneck of PCI interface, and has
excellences of high-speed, real-time, portable and massive capacity.
