Bypassing memory requests to a main memory

摘要

Some embodiments include a computing device with a control circuit that handles memory requests. The control circuit checks one or more conditions to determine when a memory request should be bypassed to a main memory instead of sending the memory request to a cache memory. When the memory request should be bypassed to a main memory, the control circuit sends the memory request to the main memory. Otherwise, the control circuit sends the memory request to the cache memory.

1. A method for handling memory requests, comprising:
in a control circuit, performing operations for:
when a memory request should be bypassed to a main memory instead of sending the memory request to a cache memory, sending the memory request to the main memory;otherwise, sending the memory request to the cache memory;wherein the memory request should be bypassed to the main memory instead of sending the memory request to the cache memory when:
the memory request is part of a sequence of memory requests that comprises one or more other memory requests; andthe memory request and a predetermined number of the memory requests from the sequence of memory requests match a predetermined pattern.
