Efficient multiple undirectional byte error-detecting codes for computer memory systems
T.R.N. Rao, G.L. Feng, Mahadev S. Kolluru · 2003
A novel method of construction of more efficient codes, which can detect t unidirectional byte errors or all unidirectional bit errors (t-UbED/AUED), is presented. In this construction, the authors generalize and improve the t-UbED/AUEd codes proposed by L.A. Dunning et al. (1990) in such a way that two weight syndromes need not be protected from unidirectional errors when t>2. Thus, this construction is more efficient and can be applied to all multiple unidirectional byte error-detecting codes.>
