Adaptive Compute-phase Prediction and Thread Prioritization to Mitigate Memory Access Latency

Abstract	The full potential of chip multiprocessors remains unexploited due to the thread oblivious memory access schedulers used in off-chip main memory controllers. This is especially pronounced in embedded systems due to limitations in memory. We propose an adaptive compute-phase prediction and thread prioritization algorithm for memory access scheduling for embedded chip multiprocessors. The proposed algorithm efficiently categorize threads based on execution characteristics and provides fine-grained prioritization that allows to differentiate threads and prioritize their memory access requests accordingly. The threads in compute phase are prioritized among the threads in memory phase. Furthermore, the threads in compute phase are prioritized among themselves based on the potential of making more progress in their execution. Compared to the prior works First-Ready First-Come First-Serve (FR-FCFS) and Compute-phase Prediction with Writeback-Refresh Overlap (CP-WO), the proposed algorithm reduces the execution time of the generated workloads up to 23.6% and 12.9%, respectively.
