Dynamic reconfiguration to support concurrent applications

Abstract

The proposed dynamically reconfigurable system can support multiple applications running concurrently. An FPGA resource manager is developed to allocate and de-allocate FPGA resources and to pre-load FPGA configuration files. For each individual application, different tasks that require FPGA resources are represented as a flow graph which is made available to the resource manager so as to enable efficient resource management and pre-loading. The impact of supporting concurrency and pre-loading in reducing application execution time is demonstrated.
