Abstract
The disclosure relates to a control mechanism for controlling access by multiple logical processors to shared resources on a common microchip. The processors attempt to reserve exclusive use of needed resources by updating a resource descriptor. The resource descriptor describes which logical processors have exclusive use of which resources. In order to update the resource descriptor, a logical processor must first obtain exclusive access to the resource descriptor by updating a semaphore.
