The Design and Implementation of Adaptive Reconfigurable Computing Array

More and more reconfigurable devices have been used to accelerate specific computation in traditional computing systems. But isolate reconfigurable system has some shortcomings such as limited computation ability, low utilization of reconfigurable devices. In this paper, a networked adaptive array of reconfigurable computing nodes was proposed, which is composed of host and reconfigurable devices. Via sharing reconfigurable resources among nodes in the system, the ability of computation of one node is enhanced and the utilization ratio of reconfigurable resources is increased. The experiment result shows that about 19.5%-48.2% execution time could be reduced by using 2-5 nodes in the array comparing with a single node for heavy workload.
