Why don the Telecomm benchmarks use floating point?
All of the kernels (Bit Allocation, AutoCorrelation, FFT/iFFT, Viterbi, Biquad IIR, Convolutional Encoder) in the suite are intended to be run (for comparison purposes) using 16-bit fixed point math. There are FP versions of some of the kernels which were used to generate the golden data file sets. At this time, we have no plans to extend the “Out of the Box” code to require/use FP math. You may re-code the kernels, using FP for an optimized version of the benchmark if you wish. At this time, we do not have access to any floating point data sets. The data sets which accompany the AutoCorr kernel are in 16-bit (1.15) fixed point format (that is: 1 sign bit, 15 bits of data) to reduce the precision of the data, you can remove (or zero) bits from the LSBs of each number.
