摘要： The present invention relates to a method and apparatus of lock transactions processing in a single or multi-core processor. An embodiment of the present invention is a processor with one or more processing cores, an address arbitrator, where one or more processing cores are configured to submit a lock transaction request to the address arbitrator corresponding to a specific instruction in response to the execution of the specific instruction. The lock transaction request includes a lock variable address asserted on an address bus. The processor further includes a lock controller for performing lock transaction processing in response to the lock transaction request, and notifying processing result to the processing core from which the lock transaction request was sent. The processor further includes a switching device, coupled to the address arbitrator and the lock controller, for identifying the lock transaction request and notifying the lock transaction request to the lock controller.

摘要： Disclosed is an interrupt dispatching system and method in a multi-core processor environment. The processor includes an interrupt dispatcher and N cores capable of interrupt handling which are divided into a plurality of groups of cores, where N is a positive integer greater than one. The method generates a token in response to an arriving interrupt; determines a group of cores to be preferentially used to handle the interrupt as a hot group in accordance with the interrupt; and sends the token to the hot group, determines sequentially from the first core in the hot group whether an interrupt dispatch termination condition is satisfied, and determines the current core as a response core to be used to handle the interrupt upon determining satisfaction of the interrupt dispatch termination condition. With the invention, delay in responding to an interrupt by the processor is reduced providing optimized performance of the processor.
