Abstract
A process of coordinating access to a shared resource by a plurality of execution units is provided. Channel control units are used to coordinate access to a shared resource. Each channel control unit reads semaphore values of a semaphore storage unit. In response to synchronization commands and semaphore values, the channel control unit manages the flow of execution instructions to the execution units in order to manage access to the shared resource.
