20130305077 | METHOD FOR SHARING A RESOURCE AND CIRCUIT MAKING USE OF SAME - A method is provided for interfacing a plurality of processing components with a shared resource. A token signal path is provided to allow propagation of a token through the processing components, wherein possession of the token enables a processing component to conduct a transaction with the shared resource. Token processing logic is provided for propagating the token from one processing component to another along the token signal path, the propagating being done at a propagation rate related to a transaction rate of the shared resource. The token processing logic also generates a trigger signal at least in part based on the token and propagates to trigger signal to the shared resource to convey initiation of a transaction with the shared resource. A circuit comprising a plurality of processing components and a shared resource is provided wherein the processing components and the shared resource interface with one another using the method proposed. | 11-14-2013 |
