RE: Benchmarks
Oops. I took a look at your page of results, and noticed that the OMAP2420 didn't really perform all that well at floating point tests, despite its having a hardware VFP (vector floating point) unit. It then dawned on me that although I'd compiled nbench with hardware fp, it had been linked against a soft-float libm. If nothing else, comparing the differences between these new results and the ones I previously posted shows how much of a difference the floating point libm makes. So here are the new results with everything hardware floating point (I've also flashed an updated image since I posted the other results, but that should make little difference): Nokia-N800-26:~# ./nbench BYTEmark* Native Mode Benchmark ver. 2 (10/95) Index-split by Andrew D.

Benchmarks
Hello all, Over at the SVHMPC, we have been benchmarking application processors. The main drive for this is that I have been working on a Freescale i.MX31 processor (based on an ARM11 core) and wanted to see how it performs compared to the competition. So far we have benchmarks for a 400Mhz PXA255, 600Mhz PXA270 and 530Mhz i.MX31. I would very much like to see how the S3C2410 and SC32442 used in the GTA01 and GTA02 stack up against the others. We may also be getting results from someone with a PXA320. If you're interested, could someone with a GTA01 (and GTA02 if possible) please compile run the benchmark? We're using the nbench software as it's easy to cross-compile. nbench is available at http://www.tux.org/~mayer/linux/bmark.html. I've posted the results we have so far on our wiki, http://hbmobile.org/wiki/index.php?title=Application_Processor_Benchmark s These are preliminary results and currently do not match what others have found, so some tweaking might be needed (especially on the i.MX31!!!). I look forward to adding more results as they come in. Cheers, Tom ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
