碩士 === 義守大學 === 資訊工程學系 === 90 === The RAID, with high throughput and reliability, is drawing more and more attention in the multimedia and network applications. With modem VLSI manufacture process and new HDD technology, the requirement of disk reliability is growing up. In the passed 20 years, most error-free technique in RAID used parity check. This technique can solve one erasure or one disk failure problem. The ENENODD[5][6] is the first method to solve two-disks failure, but the recover mode is too complex to implement in VLSI. In addition, huge cache memory is required. Reed-Solomon (RS) Codes[12][13] have the outstanding ability of error correction with little memory required. Many papers about error free of RAID tell us that the RS codes are very complex in coding and decoding[8]. In this thesis, we simplify the RS codes decoder[11] and solve the small write problem[15]. Those IPs provide transparent and real-time operation in system design. It’s more efficient to implement in VLSI and may support the SoC total solution in high-level internet-multimedia file server in the future.
