Abstract
Systems and methods for reducing data movement when performing large-sized memory transactions in a memory hierarchy are provided. For certain preselected types of large-size memory transactions, such as memset and memcopy operations, for example, logic of the processor determines whether the type of memory transaction being queued is one of the preselected types for which alteration of the path of data movement is an option. Logic of the processor also determines whether the size of the memory block associated with the transaction is sufficiently large to warrant altering the path of data movement. If the type is one of the preselected types and the size of the memory block is sufficiently large, logic of the LLC controller selects an altered path for data movement that reduces data movement and performs the transaction using the altered path.
