...st the same, eventually it would be possible to >get better performance using the ARM5E DSP-like instructions. Unfortunately the core is 920T, thus it does not implement ARMv5 instruction set. As soon as I have a working MaverichCrunch-enabled tool chain, I'll post the results.

....7 with MaverickCrunch support. To add this support I had to define CPPFLAGS as follows: export CPPFLAGS='-mcpu=ep9312 -mfix-crunch-d1' but it seems libtool does not like it, while the object files are compiled fine: ... arm-linux-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I/home/llandre/devel/zephyr/sw/rootfs/usr/local/include/ogg -mcpu=ep9312 -mfix-crunch-d1 -g -O2 -c mdf.c -MT mdf.lo -MD -MP -MF .deps/mdf.TPlo -fPIC -DPIC -o .libs/mdf.o arm-linux-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I/home/llandre/devel/zephyr/sw/rootfs/usr/local/include/ogg -mcpu=ep9312 -mfix-cr...

...4) command-line comp parameter Clearly the best solution is exploiting the MaverickCrunch coprocessor. Assuming we have MaverickCrunch-enabled GCC e glibc, do you suggest to use e full floating point implementation or to use the --enable-fixed-point anyway?

Hi llandre, I think it's worth trying the float version on your CPU. However, I wouldn't be surprised if the fixed-point was still faster than float. BTW, you can use --enable-arm5-asm instead of --enable-arm4-asm. While both are currently almost the same, eventually it would be possible to get bette...

Hi Santosh, since we are talking about speex I think we can do it on the mailing list. Other users might participate and get/provide useful information. If you want to talk about not-speex-related matters you can use this email address anyway. Regards, llandre PS: I think your mail client does not work perfectly. When you replied to my first message, it changed the subject from "Encoder performance on ARM9" to "Re:Problems with 16kHz encoding".
