This paper introduces a new methodology that characterizes aging-duty cycle and aging-supply voltage relationships that are applicable to minimizing power consumption and task execution time to achieve low Bit-Energy-Ratio (BER). In contrast to the traditional workload balancing scheme where cores are regarded as homogeneous, we proposed a new task scheduler that ranks cores according to their various...
As device feature sizes continue to shrink, long-term reliability such as Negative Bias Temperature Instability (NBTI) leads to low yields and short mean-time-to-failure (MTTF) in multi-core systems. This paper proposes a new workload balancing scheme based on device level fractional NBTI model to balance the workload among active cores while relaxing stressed ones. The proposed method employs the...
