Abstract
After presenting the translation and optimization techniques utilized by the SPL compiler, empirical data is presented showing the efficiency of the resulting C/FORTRAN code. Timings are compared, using fast Fourier transform (FFT), Walsh-Hadama transform (WHT), discrete cosine transform (DCT) and discrete sine transform (DST) as the benchmarks, to those obtained by highly optimized implementations including FFTW and the WHT package. The results of this comparison show that the SPL compiler produces code that is competitive and, in many cases, faster than the competitors.
