OK, I've updated oe.dev so that you can build gnuradio (r10302) with NEON implementation of the fff dotprod. I'm told the files should flow into the overo build system soon also. To build, (short form for people who can build their own sw), Edit the gnuradio_svn.bb and boost_1.36.bb files and comment out the DEFAULT_PREFERENCE="-1" lines with a #. bitbake gnuradio-image wait a long time. After you get it loaded, start testing :) dial_tone.py should work and the benchmark for the fff dotproduct should give you something like this: balis...@beagleboard:~/oe/tmp/work/armv7a-angstrom-linux-gnueabi/gnuradio-3.1.3+svnr10302-r6/trunk/gnuradio-core/src/tests$ ./benchmark_dotprod_fff generic: taps: 256 input: 4e+07 cpu: 1269.242 taps/sec: 8.068e+06 cortex_a8: taps: 256 input: 4e+07 cpu: 49.156 taps/sec: 2.083e+08 Note, I NFS mounted my home dir on teh beagle and ran the benchmark command on the build machine first. This needs work :) Philip _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
