APPARATUS FOR PERFORMING SINGLE ERROR CORRECTION AND DOUBLE ERROR DETECTION

摘要

SPECIFICATION OF L. G. TRUBISXY FOR APPARATUS FOR PERFORMING SINGLE ERROR CORRECTION /A DOUBLE ERROR DETECTION This relates to an apparatus for performing single error correction, double error detection of binary words, each section of the apparatus processing one byte of raw data. Each section includes first logic means for producing a first plurality of intermediate sector matrix parity outputs. A second logic means receives one of the first plurality of intermediate sector matrix parity outputs and a second plurality of intermediates matrix parity outputs from other sections and generates therefrom a syndrome signal. A third logic means receives this syndrome signal and syndrome signals from other sections and generates therefrom the corrected data bits. 5202565 5202565
