Title: Parallel processing-type error correction circuit by bch code
Inventor: TOGASHI TOSHIMITSU
IPC: H04L1/00
Filed: 1990-09-05
Abstract: PURPOSE:To miniaturize a whole circuit by correcting the error of appropriate parallel data without using ROM. CONSTITUTION:It comes to sigma1alpha<m>+sigma2alpha<2m>+...+sigmanalpha<nm> in an exclusive OR means 58 in a first table, and this corresponds to the left side of a location equation sigmanX<n>+sigman-1X<n-1>+...+sigma2X<2>+sigma1X=1. Namely, the error of a first sequence in aprallel data PD can be corrected by a detection signal DS1 outputted from the exclusive OR means 58. In an exclusive OR means 58 in a second stage, it comes to sigma1alpha<m+1>+sigma2alpha<2(m+1)>+...+sigmanalpha<n(m+1)> and sigma1alpha<2(m-1)>+sigma2alpha<2(2m-1)>+...+sigmanalpha<n(2m-1)> in an exclusive OR means 58 in an n-numbered stage. They correspond to the left side of the location equation and therefore the errors of the second sequence and m-numbered sequence in parallel data PD 2 can be corrected by detection signals DS2,..., and DSm. Thus, the whole circuit is miniaturized.
