Title : Performance Evaluation of Dynamic Circuit Specialization on Xilinx FPGAs

Authors: Prof. Dirk Stroobandt, Tom Davidson, Karel Heyse, Amit Kulkarni Venues: Copenhagen Sept. 11th; Stockholm Sept. 9th Abstract: Dynamic Circuit Specialization (DCS) is a technique used to optimize FPGA applications when some of the inputs, called parameters, are infrequently changing compared to other inputs. For every change of parameter input values, a specialized FPGA configuration is generated during run time and the FPGA is reconfigured with a specialized bitstream. We examine how the performance of the DCS technique evolves with the advent of newer Xilinx FPGA architectures. The performance of the DCS technique is evaluated on three different Xilinx FPGA architectures: Virtex-II Pro, Virtex-5 and Zynq SoC. We have used a 16-tap, 8-bit FIR filter as a parameterized design, with the filter coefficients as the parameters of the FIR design.
