Abstract
A lock controller supports both blocking and non-blocking lock requests issued by processors of a processing engine when attempting to access a shared resource of an intermediate network device. The non-blocking lock controller capability provides a processor with the flexibility to obtain other shared resources if the originally requested resource is not available. The blocking capability of the lock controller guarantees that each processor will eventually obtain the requested resource. By supporting both blocking and non-blocking capabilities, the lock controller provides increased flexibility and performance to the processors of the processing engine.
