Energy efficiency is considered to be the most critical design parameter for ubiquitous and mobile computing systems. With consumers expecting improved functionality and performance from these systems without compromising on battery life, there is urgent need to explore emerging technologies that can overcome the limitations of CMOS and deliver greater energy efficiency. The potential of one such...
Current day processors utilize a complex and finely tuned system software to map applications across their cores and extract optimal performance. However with increasing core counts and the rise of heterogeneity among cores, tremendous stress will be exerted on the software stack leading to bottlenecks and underutilization of resources. We propose an architecture for a Compilation Accelerator on Silicon...
The proliferation of ubiquitous and mobile computing systems has created a new segment in the design space where energy efficiency is the most critical design parameter. With the end user expecting more functionality from these types of systems, there is a pressing need to evaluate emerging technologies that can overcome the limitations of CMOS. This work evaluates the potential of one such prospective...
A high performance and low power node architecture becomes crucial in the design of future generation supercomputers. In this paper, we present a generic set of cells for designing complex functional units that are capable of executing an algorithm of reasonable size. They are called Algorithm Level Functional Units (ALFUs) and a suitable VLSI design paradigm for them is proposed in this paper. We...
Transistor scaling and reduction in operating voltages have resulted in cosmic-ray induced soft errors becoming a major threat for reliable processor operation. With the raw device soft error rate expected to remain constant in future generations, the explosion in on-chip transistor count is expected to have a corresponding impact on overall error rate. Consequently it becomes necessary to incorporate...
The choice of supercomputers, by the user community, should not merely be based on the benchmarks. With the advent of supercomputers delivering petaops performance, computationally intensive applications such as brain modeling and energy requirement prediction have become predominant. Conventional benchmarks do not reflect the functional characteristics of these applications. Thus, the gap between...
