Abstract

An error detection code decoding device in which information codes obtained through a transmission path and original check codes which correspond to the information codes and which are obtained through the transmission path are input. A processor receives the input information codes and forms restored check codes by using the information codes, the processor including lookup tables for inputting the information codes as addresses and reading out data regarding the restored check codes. A detector detects whether or not the restored check codes and the original check codes coincide and outputs an error detection signal indicative of the presence or absence of an error.
