Multiprocessor control synchronization and instruction downloading.

摘要

The present invention is a multiprocessor machine control having at least one processor for performing input and output operations and communicating with a master processor over a communication channel. Common synchronizing signals are conveyed to both the input/output processor and the master processor independent of the communication channel. This provides the input/output processor with immediate access to timing and synchronizing information for prompt response to general control information from the master processor. The master processor downloads instructions or provides general instructions to the input/output processor. These downloaded instructions are given priority and timely executed without further communication with the master processor. At completion of the operation the master processor is informed that the particular operation has been performed.
