Summary:PROBLEM TO BE SOLVED: To provide an error-detecting coding circuit capable of easily detecting an abnormality which may cause a generation of bit string of all "0" or all "1".SOLUTION: An error-detecting coding circuit includes: a first calculation section; a second calculation section; a generation section. The first calculation section calculates a first parity bit in a bit string of a prescribed length. The second calculation section calculates a second parity bit which has a polarity opposite to that of the first parity bit in the bit string. The generation section adds the first parity bit and the second parity bit to the bit string to generate an encoded bit string.SELECTED DRAWING: Figure 3 【課題】 オール"0"またはオール"1"のビット列を生じさせる異常を簡易に検出可能にすること。【解決手段】 実施形態によれば、誤り検出符号化回路は、第1計算部と、第2計算部と、生成部とを具備する。第1計算部は、既定長のビット列についての第1パリティビットを計算する。第2計算部は、上記ビット列についての第1パリティビットとは逆極性の第2パリティビットを計算する。生成部は、上記第1パリティビットと第2パリティビットとを上記ビット列に付与して符号化ビット列を生成する。【選択図】 図3
