Abstract
In one embodiment, an apparatus includes an input port to receive a request to determine whether data units are stored in the cache, as well as an output port to generate look-ups for the pool of tags. The apparatus also includes a look-up filter coupled to the input and output ports, and operates to filter out superfluous look-ups for the data units, thereby forming filtered look-ups. Advantageously, the look-up filter can filter out superfluous look-ups to at least reduce the quantity of look-up operations associated with the request, thereby reducing stalling associated with multiple look-up operations. In a specific embodiment, the look-up filter can include a data unit grouping detector and a look-up suppressor.
