Low-power processors require effective memory partitioning
Resumen:
The ever increasing complexity of embedded systems demands for rising memory size, and larger memories increase the power drain. In this work, we exploit banked memories with independent low-leakage retention mode in event-driven applications. The resulting energy saving for a given number of banks is close to the maximum achievable value, since the memory banks access pattern of event-driven applications presents a high temporal locality, leading to a low saving loss due to wake-up transitions. Results show an energy reduction up to 77.4% for a memory of ten banks with a partition overhead of 1%.
