Abstract: A conventional decoder of the type that converts an m-out-of-n representation to activation of only a single one of plural output lines is modified to have powerful self-checking capabilities. The modified decoder is adapted to be included in a control system in which the words stored in a microprogram memory are coded in an m-out-of-n format. Such a system automatically detects the occurrence of any no-output or multiple-output readout from the memory.

Abstract translation: 将m-out-of-n表示转换为仅激活多个输出行中的单个输入行的类型的常规解码器被修改为具有强大的自检功能。 修改后的解码器适于包含在控制系统中，其中存储在微程序存储器中的字以m-out-n格式编码。 这样的系统自动检测从存储器发出的任何无输出或多输出读出。
