This paper presents a research to strengthen the using of embedded system memory, including: Flash memory, SRAM, DRAM etc. For increasing the reliability on data storage, we use the conventional fault-tolerant mechanisms-Mirror and CRC techniques to carry out the forward protection at first. Furthermore we use the encryption and Reed-Solomon code to improve the function at back end. This article designs a simple and high speed solution based on the finite field arithmetic, let the fault-tolerant facility can tolerate one-bit error from multiple bit error or multiple column error on common memories. Then we advanced improve the speed problem of Reed-Solomon code in coding, and develop an efficient way in the VLSI architecture. Finally we adopt the embedded system of DE2 to develop the co-design coding environment to provide a complete and high reliability scheme. |
