N2 - A workload-aware low-power neuromorphic controller for dynamic voltage scaling in VLSI systems is presented. The neuromorphic controller predicts future workload values and preemptively regulates supply voltage based on past work- load profile. Our specific contributions include: (1) implementation of a digital and analog version of the controllerin 45nm CMOS technology, resulting in 3% performance hit with a power overhead in the range of 10-150 microwatts, (2) higher prediction accuracy compared to a software based OS-governed DVS scheme by 50%, reducing wasted power and improving error margins, (3) digital design has minimal power overhead and is more reconfigurable, while analog design is better suited for nonlinear and complex computational tasks.
