[Speex-dev] Speex 1.1.10 on ARM926EJ-Sid(wb) rev 3 (v5l)

[Eduardo Bezerra]

Hi all,
 


  I'm trying to use libspeex 1.1.10 on an ARM926EJ-Sid(wb) rev 3
(v5l). I executed
the speexenc and speexdec test files and they can encode and decode.
But I'm getting 95% of cpu utilization on the codification and 44% on
the decodification.
  I saw in the post:
http://lists.xiph.org/pipermail/speex-dev/2005-June/003485.html
  that this version of speex works fine on ARM platforms. My configuration
is:

# cat /proc/cpuinfo
Processor       : ARM926EJ-Sid(wb) rev 3 (v5l)
BogoMIPS        : 95.83 (about 192 MHz)
Features        : swp half thumb fastmult edsp java
CPU implementer : 0x41
CPU architecture: 5TEJ
CPU variant     : 0x0
CPU part        : 0x926
CPU revision    : 3
Cache type      : write-back
Cache clean     : cp15 c7 ops
Cache lockdown  : format C
Cache format    : Harvard

#  gcc --version
arm-linux-gcc (GCC) 3.3.2 (Debian)

Configuration: --enable-fixed-point --enable-arm5e-asm

Speex specs: Complexity 0, 8Kbps
Encoding: ~95%, Decoding: ~44%, without Echo Cancellation / Pre-processor

  Does anyone know how I can reduce this utilization? Is there any
float point code on speexenc/speexdec that wasn't converted to
fixed point?
