Abstract
A shared bus arbitration system is disclosed which provides logic allowing multiple processors to co-exist on a common bus. In the present invention, the host processor is isolated from the bus by a posted write array or write buffer. The arbitration system accepts bus lock and cycle signals when the processor writes a locked instruction to the posted write array and provides a bus lock signal to the bus when the locked instructions are written to the bus.
