Abstract
An arbiter circuit manages and enforces arbitration and quality of service (QOS) among multiple devices accessing a resource, such as a memory. The arbiter circuit receives requests from a number of devices to use resources of a bridge connecting to a memory, and maintains a count of bridge resources available on a per-device and per-bus basis. The arbiter circuit operates to select a next one of the requests to grant a bridge resource based on the device originating the request, a count of the per-device resources available, and a count of the resources available to the bus connecting the device to the bridge.
