RECONFIGURABLE RADIO WITH FPGA-BASED APPLICATION-SPECIFIC PROCESSORS
R. G. Jackson, M.P. Fitton, Steven F. Perry · 2004
FPGAs are a viable solution for the computationally intensive signal processing requirements in softwaredefined radio (SDR). The conventional approach to partially or fully reconfigure the device to meet different requirements results in an associated delay and/or overprovision of resources required. We demonstrate a new approach based on application-specific integrated processors (ASIPs) where the FPGA is configured to provide a number of functional units controlled by a simple processor and associated program. Reconfiguration then merely requires modification of the program and may be performed quickly and simply.
