Hello, I?m using the Linux Bridge on an Atmel Arm9 Plattform with the kernel 2.6.11rc3. The configuration is the following: LAN<--Arm9(Ethernet)--Bridge--Arm9(USB-Device)-->Notebook (USB-Host) or LAN<--Arm9(Ethernet)--Bridge--Arm9(USB-Host)-->Notebook (USB-Host) (with a Trust USB2.0 Host to Host cable) When I try to ping my Notebo...

...9;s consider that you'd succeed in getting it working right after optimizations. The time you want to add other speex features or other functionality you may run in trouble again. It is perhaps worth the effort only in really high-volume products... In a non-OS environment I believe an ARM9 or perhaps a Cortex-based micro with at least 150 MHz is the proper choice. For your information: it is known that (even) ARM9 @ 400 MHz has difficulties when speex is operated in a Linux environment (reference app: Linphone). And in a comparable environment a real DSP chip like Analog'...

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-...

Hello, I would like to run nut 2.6.1 on an embeeded machine ( arm9 ) running linux and uclibc. A working gcc tool chain came with the board. How can I compile and build nut using the cross compiler tool chain ? I know that this is not a very specific question. I have however little experience with cross compiling, and I wonder where to start. A logical point wou...

hi, i have searched through the archives but did not manage to find benchmarks of encoding/decoding speex on ARM processor. esp interested in ARM9E. understand that ARM5E has some dsp-like instructions, wonder whether they are compatible with those in ARM9E. thanks in advance. tk -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I have read the decoding side performance on ARM7 or ARM9. Your comment is very useful for us on evaluating the possible usage of Speex on our ARM system. How about the encoding performance? In your article, you mentioned "optimization". What is it? Is it included the 1.1.6 release source codes? thanks, Jay -------------- next part ----------...

Hi, I have one question: Will Speex run in realtime (both encode / decode probably simulateusly) on Nokia 6600 --- basicaly ARM9 104MHz with Symbian 7s after porting to its C++ or Java? I am thinking mostly about the worst quality encoding (optionally duplex). Can this processor make it? Oh 6600 has something about 6mb memory if I remember good.

...or this information, but I have not been able to gain a clear understanding: what is the status of the LLVM ARM backend? That is, do the following work: 1. Generating Thumb code: I saw a video online where they describe an issue with using the ARM Thumb back-end 2. Generating code for ARM9 (ARMv5?) or ARM7 (ARMv4): again, the same presentation mentioned that it only generated ARMv6 or 7. Does the back end work on older ARM processors today? I have seen the notes on the Apple provided bits to the project, but those were form early-mid 2007, and I have not seen a clear declaration on...

...tems that I can volunteer. - Cortex-A8 I have bunch of devices but they are only good for target testing. - Cortex-Mx ARMv7M I have myriad of boards that I use for target testing, the problem is that they can only run very small testcases. - Assorted ARMv4, ARMv5 and ARMv6 architecture or ARM11, ARM9 and ARM7 processors. Usable for host testing are the Marvell Armada/Kirkwood based Plug Computers, easy to get and I can volunteer 1. Just my 32-bits. Pawel

I haven't tried using -Os/z on any ARM device for the last 3 years, and back then, -Os would break many things. People normally care about code size on Cortex-R/M and ARM9 or older, and in there, not many LLVM users. --renato On 27 February 2013 00:38, Jim Grosbach <grosbach at apple.com> wrote: > I've not run any on non-iOS devices, and haven't looked at GCC since > v4.2.1 due to licensing issues, so I don't have a good feel for comparati...

...uestions. I've tried to do my homework reading the relevant manual pages and investigating the Doxygen documentation. :-) We're investigating acoustic echo cancellation solutions for a speech application. Our hardware will be a TI C64x+ series processor (DM6467) which has both a DSP and ARM9 core. Our audio will be sampled at 8kHz and fed in through the I2S ports on the DM6467, echo cancelled, and then encoded in G.711. As such, I'm really interested in the echo cancellation component of Speex, but not in the encode/decode. Finally, only one channel of audio needs to be echo cancel...
