Common priority information for multiple resource arbitration

An arbiter system for arbitrating between a plurality of requestors in a computing system that share a plurality of computing resources, the arbiter system comprising:

• priority selection hardware comprising:
• priority generation logic for each resource that is configured to generate priority information for a next cycle based on an arbitration scheme, the priority information indicating which of the plurality of requestors has priority in the next cycle,
• modification logic for each resource that is configured to generate relevant priority information for the next cycle by extracting from the priority information for the next cycle for that resource information that relates to requestors that requested access to the resource in a current cycle and were not granted access to the resource in the current cycle, and
• combination logic configured to combine the relevant priority information for each resource to generate common priority information for the next cycle, and store the common priority information for the next cycle in a storage unit;
• and
• an arbiter for each resource, each arbiter configured to:
• select an active requestor for the corresponding resource in the next cycle to be granted access to that resource based on the common priority information stored in the storage unit, wherein an active requestor for a resource in the next cycle is a requestor that requested access to that resource in the next cycle, and
• notify the corresponding resource of the selected requestor for that resource for the next cycle.
