Recently, manycore architectures are widely adopted for providing the increasing throughput demands and requirements imposed by software complexity and volume explosion. At the same time, the threat of Dark Silicon points to the direction of energy efficient platforms. Near Threshold Computing (NTC) paradigm has recently emerged as the premise of energy efficient operation at the expense of performance...
Continuous technology scaling and increased demand for computational power have introduced a paradigm shift in manycore design requirements. On the other hand, tight power budgets and limitations of voltage scaling are throttling the ability to optimally exploit the potential of these systems, leading researchers to adopt aggressive voltage scaling techniques such as Near-Threshold Computing (NTC)...
The power-wall problem driven by the stagnation of supply voltages in deep-submicron technology nodes, is now the major scaling barrier for moving towards the manycore era. Although the technology scaling enables extreme volumes of computational power, power budget violations will permit only a limited portion to be actually exploited, leading to the so called dark silicon. Near-Threshold voltage...
The power-wall problem and its dual utilization-wall problem are considered among the main barriers to feasible/efficient scaling in the manycore era. Several researchers have proposed the usage of aggressive voltage scaling techniques at the near-threshold voltage region, promising significant improvements in power efficiency at the expense of reduced performance values and higher sensitivity to...
