ABSTRACT:
It has been discovered that preventing performance of ineffective write operations reduces demand on memory bandwidth, as well as preventing unnecessary consumption of resources. A write operation is inspected to determine whether the write operation will effectively modify the destination of the write operation (i.e., whether a net change will occur). Those ineffective write operations are not performed. Preventing performance of the write operation includes not changing contents of locations in a memory hierarchy that correspond to the destination of the write operation.
