  • Interlock control of asynchronous data transmission between a host processor and a plurality of microprocessors through a common buffer
    Patent number: 4244018
    Abstract: An interlock circuit is set forth which provides for controlling asynchronous data transfers between a host processor and a plurality of microprocessors via a common buffer. The interlock circuit consists of an interconnection of latches arranged so that the first processor initiating a transfer request inhibits all remaining processors from activating their respective transfer requests. Each processor upon terminating a data transfer clears its associated transfer request. The host processor can clear all transfer requests upon command.
