Method for sharing a resource and circuit making use of same

A circuit comprising:

• a) a plurality of processing components;
• b) a resource component shared between the plurality of processing components;
• c) a token signal path to allow propagation of a token through the processing components in the plurality of processing components, wherein possession of the token by a given processing component enables the given processing component to conduct a transaction with the shared resource component;
• d) token processing logic for:
• i. propagating the token from one processing component to an other processing component along the token signal path;
• ii. generating a trigger signal at least in part by processing the token, wherein said trigger signal conveys initiation of a transaction between a specific processing component amongst the plurality of processing components and the shared resource component, wherein the specific processing component has possession of the token;
• iii. propagating said trigger signal to the shared resource component to synchronize communications between the specific processing component and the shared resource component at least in part by performing at least one of:
• (a) using said trigger signal to generate a clock signal for use by the shared resource component;
• and
• (b) using said trigger signal to asynchronously transfer a transaction to a shared resource.
