Abstract

1487706 Buffer storage systems PLESSEY CO Ltd 16 Jan 1976 [4 Feb 1975] 4657/75 Heading G4A A buffer storage system for use between asynchronous equipments comprises three stores S1-S3 and microprogrammed control units ISM, OSM responsive to "store full" and "no data" signals SF, ND indicating the status of each store to select one store at a time for input and a different store for output. The status indicators are set and reset by microprogram on start up, the beginning and end of an input process or output process as appropriate. An inhibit circuit IC produces signals IIS, IOS which are used by the output and input microprograms to ensure that only one process (input or output) can change store selection at a time by producing a corresponding change store selection signal CISS, COSS. The output process has priority over the input process if two store selection demands occur simultaneously. Detailed logic circuits for effecting the store selections with appropriate interlocks between selections are described.
