Approximate adders are widely being advocated as a means to achieve performance gain in error resilient applications. In this paper, a generic methodology for analytical modeling of probability of occurrence of error and the Probability Mass Function (PMF) of error value in a selected class of approximate adders is presented, which can serve as performance metrics for the comparative analysis of various...
Many-core processors exhibit hundreds to thousands of cores, which can execute lots of multi-threaded tasks in parallel. Restrictive power dissipation capacity of a many-core prevents all its executing tasks from operating at their peak performance together. Furthermore, the ability of a task to exploit part of the power budget allocated to it depends upon its current execution phase. This mandates...
In order to address the throughput constraints of the system at minimal power consumption, the workload of computing nodes should be balanced. This requires accounting for the underlying hardware characteristics and throughput sustainable by these nodes. This work provides a workload distribution and balancing methodology of a divisible load under a throughput constraint, on heterogeneous nodes. The...
On-chip last-level caches in multicore systems are one of the most vulnerable components to soft errors. However, vulnerability to soft errors highly depends upon the parameters and configuration of the last-level cache, especially when executing different applications. Therefore, in a reconfigurable cache architecture, the cache parameters can be adapted at run-time to improve its reliability against...
