Re: [Discuss-gnuradio] How to set up MP-Benchmark Test PowerPC Processo

Hi,

here is my mp-benchmark of PS3! Looks a little bit deformed at pipe 6. I'm running at the moment another test, to check out.
OK, i think this is with altivec. But now, how can i perform this test without altivec like here: http://gnuradio.org/images/perf-data-images/ps3.png

Thanks in advance for help!

Best Regards
Matty

I'm pretty sure that it uses Altivec by default on PPC.  (The only
hand coded Altivec code is in the gr_fir_fff filter.)

Do your results look like this:

or like this:

The PPC on the Cell is seriously lame, as you have no doubt found out
by now...
