  • System for generating error signal to indicate mismatch in commands and preventing processing data associated with the received commands when mismatch command has been determined
    Patent number: 5687310
    Abstract: An apparatus which provides a means of ensuring command synchronization for computer systems employing sliced gate array processors includes a computer bus, a plurality of central processing units and a plurality of input/output processors coupled to the computer bus. Each input/output processor includes means to receive commands from said central processing units. The apparatus further includes means within each of the input/output processors for generating a signal indicating the type of command received from the central processing units and means for receiving from every other input/output processor the command type signal generated by every other input/output processor. In addition, the apparatus further includes means for comparing said command type signals and generating an error signal when the comparison indicates that all of the input/output processors have not received the same command.
