Abstract: One embodiment of the present invention sets forth a technique for processing commands received by an intermediary cache from one or more clients. The technique involves receiving a first write command from an arbiter unit, where the first write command specifies a first memory address, determining that a first cache line related to a set of cache lines included in the intermediary cache is associated with the first memory address, causing data associated with the first write command to be written into the first cache line, and marking the first cache line as dirty.

Abstract: A method for managing memory traffic includes causing first data to be written to a data cache memory, where a first write request comprises a partial write and writes the first data to a first portion of the data cache memory, and further includes tracking the number of partial writes in the data cache memory. The method further includes issuing a fill request for one or more partial writes in the data cache memory if the number of partial writes in the data cache memory is greater than a predetermined first threshold.

Abstract: A system and method are described for dynamically changing the size of a computer memory such as level 2 cache as used in a graphics processing unit. In an embodiment, a relatively large cache memory can be implemented in a computing system so as to meet the needs of memory intensive applications. But where cache utilization is reduced, the capacity of the cache can be reduced. In this way, power consumption is reduced by powering down a portion of the cache.
