Abstract
Disclosed are an apparatus, a system, a method, a graphics processing unit ('GPU'), a computer device, and a computer medium to implement a pool of independent enhanced tags to, among other things, decouple a dependency between tags and cachelines. In one embodiment, an enhanced tag-based cache structure includes a tag repository configured to maintain a pool of enhanced tags. Each enhanced tag can have a match portion configured to form an association between the enhanced tag and an incoming address. Also, an enhanced tag can have a data locator portion configured to locate a cacheline in the cache in response to the formation of the association. The data locator portion enables the enhanced tag to locate multiple cachelines. Advantageously, the enhanced tag-based cache structure can be formed to adjust the degree of reusability of the enhanced tags independent from the degree of latency tolerance for the cacheline repository.
