Abstract
Context switching of hardware in an FPGA custom computer is evaluated using a signal processing application targeted at the SPACE2 architecture. It is found that both the throughput and area*time metrics of the implementaion can be dynamically varied. In an algorithm where the context switching is driven by the data input stream a form of hardware thrashing is possible. The results of the paper also show how the restriction of throughput of a CPU due to excessive interupt frequency can be removed by transferreing computing load to reconfigurable hardware.
