MEMORY AND BUS FREQUENCY SCALING BY DETECTING MEMORY-LATENCY-BOUND WORKLOADS

Disclosed are systems and methods for adjusting a frequency of memory of a computing device. The method may include counting, in connection with a hardware device, a number of instructions executed and a number of requests to the memory during N milliseconds and calculating a workload ratio that is equal to a ratio of the number of instructions executed to the number of requests to memory. If the workload ratio is less than a ratio-threshold, then the memory vote is determined based upon a frequency of the hardware device. A frequency of the memory is managed based upon an aggregation of the memory-frequency vote and other frequency votes.
