performance speex on ARM
Well,
all ARM9E cores use the v5TE architecture, which means Thumb
and DSP-friendly instructions.

Port speex to my iPAQ 1945
Hi
I want to port speex to my pocket PC iPAQ1945 which has a Samsung
processor 2410, an ARM9-based processor. I would like to write the
specific optimized code for this chip. I had some experience at DSP
chip and fixed-point coding but know nothing about embedded system and
ARM. Could someone tell me some hint how to write optimized code for
this pocket PC. If you can give me some links that will

Encoder performance on ARM9
Hi there,
I've just started to work with the great speex encoder on ARM9-based
embedded platform. This is my configuration:
CPU: Cirrus Logic EP9315 @ 200 MHz (ARM920T)
o.s.: Linux 2.6.9-rc2-ep93xx
GCC: gcc version 3.3.3 (DENX ELDK 3.1 3.3.3-10) without MaverickCrunch support
ogg library: 1.0
speex command line configuration: ./configure --enable-fixed-point
--enable-arm4-asm
The code is

SPEEX Fixed Point Development
We are in the process over the next week to implement the Fixed Point
algorithms into a 200 MHz ARM9 CPU with MMU and I was wondering if you had
any experience/knowledge with possible pitfalls. We are running Fixed Point
compilation on PC based system (P4 processor) and are noticing that the
audio gets "noisy" and then comes back to a more normal voice. Are you
aware of any issues with

Static linking without C runtime dependence?
Hi,
I'm writing a Speex-based IP interview tool.
What's cool (and unique) about it is that since the goal is a perfect
_recording_ of an interview, rather than a perfect real-time experience, I
can afford to skimp on jitter buffer and redundant speech samples in favor
of lower interactive latency ... and incorporate a speech sample
retransmission protocol so that the receiver can ask

Big GAP of speex MCPS on arm CPU and RVDS simulator
Hi all Speexers,
I've done some optimization to current SVN fixed-point on ARM9E platform.
If the RVDS simulator gives the MCPS(Million Cycle Per Second) value A,
then actual MCPS on real CPU will be around 2*A.
I don't know what cause the big gap between the simulator and real CPU.
What do you think?
BR,

speex optimisation for ARM 5TE architecture
Hello everyone,
Can any body please tell me the compiler options to optimise the speex code for ARM TE architecture. Fixed point is enabled. It currently takes about 700ms to encode 5 sec worth of voice. I need to get it down to under 10ms.
Is the option --enable-arm5te-asm supported? I am using speex 1.1.12 version. The configure.ac file does not seem to support --enable-arm5te-asm

Running a dovecot cluster with mixed versions?
I have been trying to find information and possible issues with running a cluster of dovecot server with different versions without any luck.
We have an existing cluster with dovecot v1.1.10 and tried migrating to a new cluster with dovecot v2.0.12. We ran into some issues when we moved traffic to the new cluster and have been unable to reproduce it in our own testing. We may need to put real

[LLVMdev] ACE claims better result than LLVM for ARM 9 ?
ACE issued following PR:

Weird that they don't give any number and use ARM 9, do they mean cortex-a9 ?

Speex for armv6
Hello,
I am trying to build a speex library file for armv6 on intel MAC OS.
I've also put -enable-arm5e-asm whether arm5e-asm works or not.
./configure -prefix=/Users/mijin/temp -disable-shared -enable-static -
enable-fixed-point -enable-arm5e-asm
This gives below errors.

Port to uClinux
Hi,
I'm trying a quick port of this terrific codec to uClinux, a Linux-derivate
for mmu-less systems. I'm particulary interested in the alloc()'s the
library does, and it's stack usage.
In nb_celp.c I found two lines of code doing memory allocation :
nb_celp.c: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float));
nb_celp.c: st =

memory usage
Hi
I am currently trying to port speex v1.1.6 to a microcontroller with
very limited memory (<64Kbyte RAM).
what I found when initialising the encoder, a chunk of 32Kb was
attempted to be alloced, which failed:
src/nb_celp.c:
void *nb_encoder_init(const SpeexMode *m)
{
/* snip */
st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(spx_sig_t));

}

TI Davinci DM Serias

My questions are:
1. What is the best ./configure option for it? Is it ARM5e / ARM4 ?
when I tried these two the during the compiled a warning
"I suppose you can have a [ARM4/ARM5E/Blackfin] that has float
