Spintronic memories are promising candidates for future on-chip storage due to their high density, non-volatility and near-zero leakage. However, the energy consumed by read and write operations presents a major challenge to their use as energy-efficient on-chip memory. Leveraging the ability of many applications to tolerate impreciseness in their underlying computations and data, we explore approximate...
Due to increased demand for higher performance and better energy efficiency, MPSoCs are deploying heterogeneous architectures with architecturally differentiated core types. However, the traditional Linux-based operating system is unable to exploit this heterogeneity since existing kernel load balancing and scheduling approaches lack support for aggressively heterogeneous architectural configurations...
Diminishing benefits from technology scaling have pushed designers to look for new sources of computing efficiency. Multicores and heterogeneous accelerator-based architectures are a by-product of this quest to obtain improvements in the performance of computing platforms at similar or lower power budgets. In light of the need for new innovations to sustain these improvements, we discuss approximate...
Heterogeneous architectures have emerged as a promising solution to enhance energy-efficiency by allowing each application to run on a core that matches resource needs more closely than a one-size-fits-all core. In this paper, an ElasticCore platform is described where core resources along with the operating voltage and frequency settings are scaled to match the application behavior at run-time. Furthermore,...
