Blackfin port on Visual DSP, Michael Shatz ?
Hi, I'm using the Speex codec on my Blackfin-based board, and plain-C performance is pretty poor. Decoder is OK (something 25 MIPS for wide-band). But Encoder is not (wide-band quality 8, complexity 1): - 162 MIPS with Analog-Devices lib - 128 MIPS with 1.2beta2 (faster but not working) I don't worry that much, as it's not the optimized version, and everything is running in SDRAM.

Patch for Analog Devices compiler & fixed-point AGC
Hi Jean-Marc, As I told you, bank is a reserved keyword in Analog Devices compiler for Blackfin architecture. So we need to change the variables named bank to something else. Here's a patch that changes bank to bnk in the 3 concerned files. (Hope the format is OK) About my previous problems with the Blackfin: -> strange block repetition that could be cancelled by the AEC I was busy

How about you just compile with -Dbank=bnk ? Yep it's working. What about including these 3 lines in arch.h ? #ifdef __ADSPBLACKFIN__ #define bank bnk

VisualDSP++ with enabled BFIN_ASM
Hi I'm trying to integrate your speex codec on our custom Blackfin board and without uCLinux. I am using ADI-supplied VisualDSP++ IDE and corresponding toolchain. My question is: Is there anybody who ported speex with enabled BFIN_ASM to VisualDSP++ ? Best Regards, Stefan Voss -------------- next part -------------- An HTML attachment was scrubbed... URL:

upssched does not start the script when timer triggers
Hello, I'm using nut with my MG Ellipse on serial port. No problem since one year. Two days ago, I wanted to add a phone alert through my asterisk box when power is down. Since then, upssched doesn't make his job anymore. here is the "syslog" I get when the power cord is unplugged : > > May 9 11:39:34 serveur upsmon[6411]: UPS ellipse@localhost on battery > May 9

Several anomalies - Samba ADS member computer
We've setup PC (700 MHz - 512 megs memory) running Samba - 3.0.21c as a test machine. We've successfully joined the machine to our Active directory using net join ADS... I'm able to create the shares, and access them. I've notice the following. 1. When I run getent passwd and getent group, I get just the local passwd and group info, nothing from the domain and no error message.

ads_connect: Program lacks support for encryption type
I'm trying to setup here at my school board an ADS domain member to Windows 2000 Server(s). I've setup Samba, configured nsswitch and /etc/krb5.conf. I'll be including them on this post. When I run << net join ADS -U<administrative_user>, I'm prompted for the password and I get this error message: [2006/01/12 15:21:35, 0] utils/net_ads.c:ads_startup(191)

FW: Re: Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h / resampler saturation???
Hi Jean-Marc, didn't get a reply to my last post (see below) -- do you have no idea what happens here? After some more tests, I disabled the DIV32_16 Blackfin optimizations and now get good quality on the Blackfin. But when I have overdrive on the input, things become very bad -- I'm not sure if this is really a filter stability issue like I wrote some weeks ago. I use the speex

bluetooth headset/handsfree
Hi *, is anybody using a bluetooth headset with some success?? If yes, which stuff is used (usb dongle and BT headset)? (I would like to : 1. be able to receive calls, if possible to answer acalls with the headset. 2. be able to place call, but this seem lot more difficult.) Laurent

indication tones and callwaiting chirp too loud
I am wondering if anyone could help me figure out how to turn down the volume on all the dial tones, indications, etc.. and especially the call-waiting CHIRP! I don't want to change the txgain and rxgain because they are working at levels that I would like. However, when voice conversations and voicemail recordings are at good levels then the dial tones, busy tones, etc are way too loud.

Using predict()?
I'm trying to solve a homework problem using R. The problem gives a list of cricket chirps per second and corresponding temperature, and asks to give the equation for the linear model and then predict the temperature to produce 18 chirps per second. So far, I have: > # Homework 11.2.1 and 11.3.3 > chirps <- scan() 1: 20 2: 16 3: 19.8 4: 18.4 5: 17.1 6: 15.5 7: 14.7 8: 17.1 9: 15.4

Frank Lorenz a ?crit : > And yes, the same "overflow" happens even when I disable Blackfin ASM > optimizations. Indeed, that shouldn't happen. Just to make sure I understand, so far there's two problems: 1) DIV32_16() in Blackfin assembly causes problems 2) The resampler overflows When you fix/workaround those two, is the encoder/decoder working correctly or are there
