Zusammenfassung:Techniques are disclosed relating to caching for address translation. In some embodiments, address translation circuitry is configured to process requests to translate addresses in a first address space to addresses in a second address space. The translation circuitry may include cache circuitry configured to store translation information, arbitration circuitry configured to arbitrate among ready requests for access to entries of the cache, and hazard circuitry. The hazard circuitry may assign a first request to an ready status the arbitration circuitry based on detection of an absence of hazards for a first address of the first request and add a second request to a queue of requests for the arbitration circuitry based on detection of a hazard for a second address of the second request. Independent arbitration for requests without hazards may improve performance in various aspects, relative to traditional techniques.
