This thesis presents the implementation and performance figures for the fast Fourier transform on an FPGA-based custom computer. The computation of a 2-D FFT requires O(N²log₂N ) complex floating point arithmetic operations for an NxN image. By implementing the FFT algorithm on a custom computing machine (CCM) called Splash-2, a computation speed of at least 180 Mflops and a speed-up of 23 times over a SPARC-10 workstation is achieved.ix, 75 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1995.S448Thesishttp://scholar.lib.vt.edu/theses/available/etd-10072005-094832/
