This document summarizes a reconfigurable system with Linux load on an FPGA. It discusses the software architecture including socket communication, device communication, and architectural layers/details. It then describes the reconfiguration of the FPGA with Linux, including module loading/unloading. Performance results are provided for startup, driver setup, and module/data loading. Finally, future work is discussed around improving algorithms, adding Ethernet support, and a distributed scenario.
