Abstract
Method and apparatus are disclosed which increase resource efficiency by collapsing writebacks to a memory. In general the method and apparatus receive an address of a memory request and compare that address to addresses of writebacks stored in a memory controller in order to determine whether the memory request maps to the same memory line of the memory as a stored writeback. If (1) the memory request generates a writeback, and (2) the memory request maps to the same line in the main memory as one of the stored writebacks, then the writeback generated from the memory request may be collapsed with one of the stored writebacks, thus reducing the number of writes to the main memory.
