More Information
Summary:Systems and method for arbitrating requests to a shared memory system for reducing power consumption of memory accesses, comprises determining power modes associated with memory channels of the shared memory system, assigning priorities to the requests based at least in part on the power modes, and scheduling the requests based on the assigned priorities. Latency characteristics and page hit rate are also considered for assigning the priorities.
