Sustained Data Recording System Based on Software RAID

摘要

The architecture and design of the recording system based on software RAID, which consists of embedded processor Intel 386EX, SCSI I/O Processor LSI 53C770, Xilinx logical control modules and SCSI hard disk drivers is presented. The dual-page buffer technology is adopted to implement speed-matching function and satisfy the need of sustainable recording. Experimental results show that the system can record the 100Mbits/s sustained data stream reliably. This embedded recording system can be used conveniently in many areas of data recording, storing, playback and remote backup.
