A generalization of the single b-Bit byte error correcting and double bit error detecting codes for high-speed memory systems

摘要

In this paper, a general method using the subsets (generating sets) of GF(2/sup b/) for constructing the SbEC-DED codes will be presented. The constructions given in Fujiwara and Hamada (1992) are special cases of ours. For some values of b, the generating sets used in our constructions are larger than the cosets used in Fujiwara and Hamada (1992). Hence, a larger code length can be obtained.
