Abstract: Error detection for an associative directory or translator, composed of registers, comparators, and encoder which provides a binary code representation of the location of the register at which a compare occurred, includes a random access register array which responds to the coded location information to read out binary data to be compared with the binary data utilized in the associative compare of the directory or translator.

Abstract: A microprogram control subsystem discloses two control stores, one of which is accessed and utilized only on the first cycle of a microprogram sequence utilized to execute an information handling system instruction. A portion of the operation code of the system instruction is used to address the first-cycle control store to provide access to a microinstruction having fewer binary bits than normal microinstructions, and is effective to direct access to the remainder of the microprogram sequence contained in the other control store.
