Kernel scheduling in reconfigurable computing

Abstract

Reconfigurable computing is a flexible way of facing with a single device a wide range of applications with a good level of performance. This area of computing involves different issues and concepts when compared with conventional computing systems. One of these concepts is context lending. The context refers to the coded configuration information to implement a particular circuit behaviour. An important problem for reconfigurable computing is the scheduling of a group of kernels (sub-tasks) that constitute a complex application for minimum execution time. In this paper, we show how the different execution orders for these sub-tasks may result in varying levels of performance. We formulate an analytical approach and present a solution for this new problem through this work.
