Abstract
This paper describes the development of a dynamically
reconfigurable system that can support multiple applications running
concurrently. A dynamically reconfigurable system allows hardware
reconfiguration while part of the reconfigurable hardware is busy
computing. An FPGA resource manager (RM) is developed to allocate and
de-allocate FPGA resources and to preload 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 RM so as
to enable efficient resource management and preloading. The performance
of using the RM to support several applications is summarized. The
impact of supporting concurrency and preloading in reducing application
execution time is demonstrated
