Control and Configuration Software for a Reconfigurable Networking Hardware PlatformPage 11Control and Configuration Software for aReconfigurable Networking Hardware PlatformTodd S. Sproull John W. Lockwood David E. TaylorApplied Research LaboratoryWashington UniversitySaint Louis MO 63130Web: http://www.arl.wustl.edu/arl/projects/fpx/ AbstractA suite of tools called NCHARGE (Networked Configurable Hardware Administrator for Reconfiguration and Governing via Endsystems) has been developed to simplify the codesignof hardware and software components that process packets within anetwork of Field Programmable Gate Arrays (FPGAs). A key feature of NCHARGE is that it provides a highperformance packet interface to hardware and standard Application Programming Interface (API) between software and reprogrammable hardware modules. Using this API multiple software processes can communicateto one or more hardware modules using standard TCP/IP sockets.NCHARGE also provides a WebBased User Interface to simplifythe configuration and control of an entire network switch that contains several software and hardware modules.I. INTRODUCTIONAn experimental platform called the Field Programmable Port Extender (FPX) has been developed toenable the rapid deployment of hardware modules in networks 1] 2]. In this system data are processed by reconfigurable hardware while control and configuration of thenetwork system is implemented in software. Control cellsare used to communicate between the hardware and software.A suite of tools has been developed to manage thenetwork of reconfigurable hardware on the FPX calledNCHARGE (Networked Configurable Hardware Administrator for Reconfiguration and Governing via Endsystems). NCHARGE enables new hardware modules tobe dynamically deployed onto the Field ProgrammableGate Array (FPGA) logic of the FPX over a network.Once the hardware module is installed NCHARGE controls the operation of each FPX by issuing customizedcontrol cells to control each hardware ...
