Performance Comparison of Graphics Processors to Reconfigurable Logic: A Case Study

By Ben Cope, Peter Y.K. Cheung, Wayne Luk, and Lee Howes

Featured article thumbnail imageA systematic approach to the comparison of the graphics processor (GPU) and reconfigurable logic is defined in terms of three throughput drivers. The approach is applied to five case study algorithms, characterized by their arithmetic complexity, memory access requirements, and data dependence, and two target devices: the nVidia GeForce 7900 GTX GPU and a Xilinx Virtex-4 field programmable gate array (FPGA). Two orders of magnitude speedup, over a general-purpose processor, is observed for each device for arithmetic intensive algorithms.
