Abstract
A method for preforming memory prefetching is disclosed. A stream length histogram (SLH) is initially generated based on a stream of Read and Write requests intended for a system memory. A determination is then made whether or not to issue a prefetch command after a Read request based on information within the generated SLH. In a determination that a prefetch command should be issued, prefetch command to be sent to the system memory is issued along with other commands.
