Abstract
A mechanism enabling a processor in a multiprocessor complex to function as a coprocessor to execute a specific function. The method includes a mechanism for activating a coprocessor to function as a coprocessor as well as a mechanism to execute a coprocessor request on the system. The present invention also provides a mechanism for efficient processor to processor communication for processors coupled to a common bus. Overall system performance is enhanced by significantly reducing the use of hardware interrupts for processor to processor communication.
