Abstract: A plurality of resource requesters may be configured to consume a resource to perform a task. Each of the plurality of resource requesters can be allocated a resource budget to consume the resource to perform the task. An arbiter can select one of the plurality of resource requesters to consume the resource based on an arbitration scheme. When a resource requester is selected, the amount of resource consumed by the resource requester can be deducted from its resource budget. When the resource requester is idle for a number of cycles when selected, the corresponding resource budget can be further reduced to account for the actual amount of resource consumed and wasted by the resource requester, which can provide fairness in resource consumption over few rounds of arbitration.

Abstract: An address decoder for a system is disclosed that can be used for different source nodes in the system. Each address decoder can be configured to perform a plurality of decode methods that can be customized for each source node. A first decode method can be used to determine a target node from a plurality of target nodes based on a destination address of the transaction. A second decode method can be used to assign a dedicated target node as the target node irrespective of the destination address of the transaction. The second decode method can be used to route the transaction to the dedicated target node for testing and verification operations.
