ABSTRACT:
Asynchronous computation commands sent from a command control are held in a command queue. The executable command is selected and supplied to a pipelined asynchronous computing unit. A status area is assured for each command held in the command queue and pipeline bits indicative of a progressing state of the execution of the command in the asynchronous computing unit are stored. A queue verifier discriminates the pipeline bits and verifies that a plurality of pipeline stages does not exist in the status area of the same command and that a plurality of pipeline stages does not exist among the commands, thereby guaranteeing the correct order and operation of the execution of the commands.
