Since OMAP UART has a few distinct features than common 8250 UART, I re-implemented its driver rather than porting it based on ns16550.c. There are mainly two big differences between the implementations. First, OMAP UART introduces the concept of register access mode, which divides the register map into seperated space. Switching the access mode is then necessary when configuring it. Second, THRE

<with Prof. Farnsworth voice> "Good News, everyone". I've just kicked off project "Sphinx". Which is supposed to sound like "Speex" merged with "INT". ;) Meaning I am working on an integer encoder and decoder. It looks like I will be pulling in a new "integer plumbing" into the foundation of the codec, comparing the results with the old

We're having problems with FreeBSD 5.4, 6.0, and 6.1 and an ICP Vortex GDT8546RZ 4 port SATA RAID card in a Tyan S2460 system with dual AMD Athlon MP 1600+ CPUs. We do not have any problems with this configuration under FreeBSD 4.11, and we have the same ICP cards in Tyan based Opterion system (S2882 and S4882) run with out problems under FreeBSD 5.4 and 6.1. We can reproduce the problem on

Hi, I have a 4.7-RELEASE system. I used the following cvsupfile to update my system: *default host=cvsup2.FreeBSD.org *default base=/usr *default prefix=/usr *default release=cvs *default tag=RELENG_4_8 *default delete use-rel-suffix src-all *default tag=. I then proceeded to do: cd /usr/src make buildworld I got a bunch of errors which occurred when building kdump:

When I tried to compile the vorbis module as a Framework, using ProjectBuilder, I got 1058 warnings (excess elements in scalar initializer, near initialization for ''psy_set0.toneatt', 'vorbis_ftoi' defined but not used, unused variable 'k', braces around scalar initializer, and so on) and 65 errors. Some examples of errors: ------- vorbis/lib/psytune.c: undefined

John, Thanks for the reply! You mentioned output sample rates should be 44100 or 48000, should I worry about input (Mic) Sample rates as well? (Currently I was requesting the sample rate on both ends to be 16000 samplesPerSecond, for ease of passing into the codec) Also, do you recommend any particular resampler that I should use, or are any of the ones out there probably okay, or should

See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. As before several of the patches are not to be applied because they can be done better using infrastructure from Julien''s "Allow Xen to boot with a raw Device Tree" patch. They are included for completeness. With

Hi! I have some questions about that functions: fir_mem16, iir_mem16 and filter_mem16. Filtering is very slow on TI DSP, and i want to optimise it. Can somebody give me formulas which discribe work of this filters? Or any suggestions about how to transform code for better performance. I going to implement this functions in assembler, but it is hard to do without full understanding how functions

That article is a bit too dismissive. I agree that one cannot hear the difference between 48KHz/16bit and 192KHz/24bit if you just transfer the data directly to the audio output device. As such, there is no good reason for Opus to support higher than 48KHz (especially since this is lossy compression, anyway). However, in general, that's not all you do with audio data. 192KHz is useful for

Hello, For some reason, I thought little about the "clear" command today.. Let's say a privileged user (root) logs on, edit a sensitive file (e.g, a file containing a password, running vipw, etc) .. then runs clear and logout. Then anyone can press the scroll-lock command, scroll back up and read the sensitive information.. Isn't "clear" ment to clear the

Compared to todays PDAs the GameBoy Advance (GBA) is low spec. it has a 16MHz ARM7tdmi RISC processor. 32-bit but it can handle 16-bit instructions in a mode that resembles "bytecode" (a 32-bit instruction is executed using a 16-bit instruction). I got a feeling that the GBA would need a FPU. For more information on the GBA visit this info page:

Hi, IIR/UC there have been a couple of discussions lately about possible evolution of libvirt's network management features to eventually support more kinds of virtual networking technologies like Openvswitch, VDE,... Could a kind and informed soul keep us on touch with progress in the field ? Thank you very much in advance PS: I wish this will be available before/for 1.0 release...

Hi, I'm speech recognition researcher and would like to do some research on recognition robustness in echo distortion of speech signal. Since VOIP is becoming wide spread, I'd like to simulate (one or more) common echo distortions that mostly appear in voip communications ? Any example, FIR or IIR filter or acoustical system response ? Any other distortion worth researching ? Thanks

It looks like the Mac .exp files were not updated for RC3. The following diff corrects that problem. The CodeWarrior project files also have not been updated. They are in 5.3 format which is quite old. Would anybody object if I submitted updates to them in CodeWarrior Pro 6 format? That's the oldest version I have readily available. If someone else has 5.3 and wants to do it, you need to

Hi Jean-Marc Thanks, >>>> I've never measured that, but it shouldn't take too much space, especially if you disable all the code (and possibly codebooks) that aren't used. so the 100kbyte ROM value quoted by Tom in his earlier mail should reduce if I cut out all the encoder code?

So, it turns out (and another implementation actually explicitly mentions it) that LSP->LPC computation using the FIR algorithm is very sensitive to noise (iterative algorithm) and really really requires doubles [we're not kidding]. This was complicating things for folks pursuing fixed point implementations, and also was a potential source for bugs if FP optimizations got out of hand. This
