Book Description
"Reed-Solomon error correcting codes (RS codes) are widely used in communication and data storage systems to recover data from possible errors that occur during data transfer. A growing application of RS codes is Forward Error Correction (FEC) in the Optical Network (OTN G.709), which uses RS(255,239) to support the OTU-3 (43.018 Gbps) standard. There have been considerable efforts in the area of RS architecture for ASIC implementation. However, there appears to be little reported work on efficient RS codec (encoder and decoder) for Field Programmable Gate Arrays (FPGAs), which has increasing interests in industry. This thesis investigates the implementation and design methodology of the RS(255,239) codec on FPGAs. A portable VHDL codec is developed and synthesized for Xilinx's Virtex4 and Altera's StratixII. The FPGA architectures are analyzed and the required design methodologies are adopted to efficiently utilize the available resources. Unfortunately, due to the fixed size of FPGA devices, the RS decoder is not only constrained by the required timing of the system, but also by the size of the targeted device. This research will facilitate the decision-making process for selecting a reconfigurable device for a RS decoder, implementing the Berlekamp-Massey Algorithm"--Abstract.

Book Description
Abstract: Soft errors caused by radiation are a common problem in spaceflight due to the intense radiation environment of space. Single Error Correction (SEC) Error Correcting Codes (ECCs) are a traditional approach to solve this problem, but with the increasing density of IC architectures, multiple-bit errors are becoming more common. Double Error Correction (DEC) ECCs are costly, but codes between DEC and SEC, which take advantage of the spatial locality of bit errors and correct only adjacent double-bit errors, have been found by others. In this thesis, one of those codes is implemented and evaluated on a Spartan-6 FPGA. The results of several error trials are presented herein, along with implementation details, including the source code. Tables of the trial results and the specific FPGA resources used are also presented. The implementation is found to have a non-negligible area cost, but low latency cost. Another implementation of this same ECC with potentially low area but high latency is also described. When errors well beyond the ECC's capability, such as multiple single-bit errors, or four-bit errors, are injected, around 30% of the time the code erroneously claims to have fixed an error. In these same circumstances, however, the ECC implementation hardly ever (0.2%) claims that no error has occurred. This suggests that a simple extension to a more conservative ECC which flushes data on any error could be used in situations with error rates that surpass the ECC's capability to maintain data integrity.

Book Description
Good error control performance requires the scheme to be selected based on the characteristics of the communication channel. Consequently, error-detecting and correcting codes can be generally distinguished between random-error-detecting/correcting and burst-error-detecting/correcting. Cyclic codes have favorable properties in that they are well suited for detecting burst errors. The cyclic redundancy check (CRC) is an error detection technique that is widely utilized in digital data communication and other fields such as data storage, data compression, etc. The work presented in describes the FPGA implementation of a CRC Decoder that has the advantages of correcting more than one bit error. Since we are introducing the hardware implementation of CRC with error correction, our main concern is about the design of the CRC decoder with error correcting capabilities. Such an optimized circuit represents an attractive hard macro for environments requiring low cost hardware flexibility, and in emerging areas such as ISCSI-based SANs, where the flexibility to adopt emerging protocols offers a key advantage to vendors.
