DescriptionBatteryless technology evolved to replace the battery. Energy harvesting devices are one promising alternative solution. Non-volatile memory (NVM) based processors were explored to store the program state during a power failure. NVM helps to store the volatile contents during a power failure. However, the time required to backup is not bounded. This paper proposes a Bounded backup time architecture (Bounded BaT) to manage the number of blocks at L1 to reduce the backup size. Bounded BaT decreases energy consumption by 12.18%, the number of writes to NVM by 14.31% at LLC and 8.23% at a main-memory level compared to baseline.
