Abstract
Access control to protected resources in a multiprocessor system is implemented without additional use of the processor bus. A bridge interconnects each processor with shared resources. The bridge has a semaphore corresponding to each protected resource indicating if the corresponding resource is available. The bridge halts a processor requesting access to any resource having a corresponding semaphore indicating the requested resource is not available.
