Hi Dave. I had a little play with cortex-strings and did some
benchmarks on my Tegra 2. Images are attached.
I've added two scripts to cortex-strings:
scripts/bench-all.sh runs all the routines on all variants and records them
scripts/plot.py plots the results from above
ploy.py corrects for the benchmark overhead by doing a linear fit to
the null 'bounce' results and subtracting this fit.
You should be able to a autogen; configure; make; bash
scripts/bench-all.sh | tee log.txt; python scripts/plot.py log.txt.
I'm sure you have your own favourite tools though.
The string routines look good. Lumpy in funny ways though...
