摘要：
Using a system of combined PC and LSI is useful when a research environment does not allow using supercomputers and calculation objects are restricted. FPGA is different from ASIC. A circuit in FPGA can be designed and reconfigured with PC or workstation electrically. We designed and implemented a circuit for 8x8 two-dimensional 2-radix FFT in a FPGA and compared its calculation speed with that of a PC. As a result, the calculation speed of the FPGA was found to be 1.3 times faster than that of a PC. (C) 2008 Elsevier B.V. All rights reserved.
