Findings

FPGA logic can be reconfigured during operation.

Application performance improves with dynamic reconfiguration.

Resource utilization adapts to changing usage patterns.

Abstract

In order to make full use of heterogeneous hardware, it is necessary to have a technical skill of hardware such as OpenCL, and the current situation is that the barrier is high. Based on this background, I have proposed environment-adaptive software that enables high-performance operation by automatically converting application code written for normal CPUs by engineers according to the deployed environment and setting appropriate amount of resources. Until now, I only considered conversions and settings before the start of operation. In this paper, I verify that the logic is reconfigured according to the usage characteristics during operation. I confirm that the application running on the FPGA is reconfigured into another application according to the usage characteristics.
