OPUS in embedded platform
Hello, I am interested in porting OPUS to an embedded platform. The idea is that the encoder and decoder will run on different processors. In order to choose the proper platform, I need an estimate of the resources which are needed for OPUS. I read the following in the OPUS wiki: "The Opus code base is written in C89 and should run on the vast majority of recent (and not so recent) CPUs.

opus Digest, Vol 52, Issue 15
Hello All, We have been doing an optimised port of OPUS to a ARM Cortex A9. We are currently measuring between 20 and 90 MCPS for our code running on a Panda board (single core), this covers all bit-rates,sample rates for stereo coding (encode + decode) under normal operation. As Marc says complexity can be controlled via the API with our higher figure corresponding to the default setting of

Build Opus on Windows
Hello, I just started into the world of OPUS. I would like to know what is the best way to build the Opus library and Opus tools on a Windows 7 pc. I see that the Opus library and the Opus tools packages have a few Makefiles. It also mentions mingw as an option for building. Is it somewhere explained what are the steps needed, or does anyone have some tips? Thanks, Met vriendelijke

DSPs which are suitable for porting OPUS
Dear Christian van Bijleveld, You can use any of the below DSPs of Texas Instruments 1. TMS320C674x - This supports floating point implementation of opus 2. TMS320C66x - This supports both floating and fixed point implementations 3. TMS320C64x - This supports only fixed point implementation Regards, Mahantesh On Mon, May 13, 2013 at 10:12 PM, <opus-request at xiph.org> wrote: >

OPUS on Cortex-M4
Hi, I would like to use OPUS codec to compress and decompress an audio stream for full-duplex intercom application; I would like to use a microcontroller equipped with Cortex-M4 core without NEON running at 72MHz. Does the OPUS codec works fine on that architecture? Do you have some benchmark data? Thank you in advance. Best regards. Daniele -------------- next part -------------- An HTML

Minimum files for building an embedded Opus library
Dear sirs, I'm trying to build an Opus library for an embedded application to run on a Microchip PIC32MX processor and I get a lot of errors in compilation time. My question is, what should be the minimum files and options needed to have such building, having in mind that only the very basic functionality in fixed point arithmetic is needed? Looking forward to your answer. Kind

Opus decoding performance on ARM devices
Hi everyone, I have lately been evaluating the performance of various audio decoders, particularly for ARM devices (Cortex A8 / A9). The context is audio playback in a game engine, and thus decoding performance is of particular interest. Looking at Opus versus Vorbis on a Cortex A9 smartphone, the numbers look approximately like this: Vorbis (tremolo decoder) 9.3 Mb PCM/s Opus (libopus 1.1)

Opus configuration for ARM cortex M7
Hi, I'm planning to use Opus codec on a ARM cortex M7 device running at 400MHz. Con you please suggest the best configuration directives that I have to set in the config.h file in order to obtain the best perfromances on the cortex M7 architecture? Actually I have compiled libopus 1.2.1 with the following cnfiguration parameters: #define VAR_ARRAYS  1 #define FIXED_POINT  1 #define

Opus encoder decoder MIPs Info Needed
Dear , We are developing embedded solutions based on the Cortex-M4. We are considering Opus as a solution for our audio compression algorithm. However,before we invest heavily in code integration we would like to get some idea of the MIPS required. Does anyone have any knowledge of the MIPs requirements for Opus (specifically the SILK portion)? what about OPUS_SET_COMPLEXTY(x) corresponding

Trying to use Opus in an STM32F429IIT6 embedded project
Hi everyone, I'm trying to use Opus in an Embedded Project which I'm developing in a STM32F429IIT6 microcontroller. Currently, I'm playing wav files in it. I ported all the files from OpusLib 1.1.4 needed to compile the project, but when I try to create and OpusDecode state, it returns the error -7 (OPUS_ALLOC_FAIL). I'm compiling it with the USE_ALLOCA flag. I also tried to

Opus decoding performance on ARM devices
Hi, Thank you for your response. I pulled yesterday to commit da97db1ca1f92592af3534c9a2596da0e9a009ca, added a bunch of more defines to my compile options, and assembled & linked in armopts.s,celt_pitch_xcorr_arm.s. Performance jumped up from about 4.8 Mb/s to 5.3 Mb/s on the same device, so it is improvement. Not sure what other tweaks there would be to try, but if it could match the

Opus performance on Cortex-M4
I'm considering implementing Opus as the codec for an embedded ARM-based battery powered audio system. In the interest of battery life and board footprint I'd like to specify the smallest CPU that can do the job. In some quick testing on Cortex-A8 (a very different core, but at least ISA compatible and hopefully fairly similar to M4 for things like cycle counts and code size) I saw

Build opus for STM32
Hello everyone. I would like to use the opus codec in the following scenario: the PCM audio signal, coming from bluetooth module is captured by STM32F446 MCU and then decoded by opus codec. However, I don't know where to start to build the opuslib for ARM Cortex-M4. Could someone provide any hints or give any brief guide on this? WBR, Aleksandr -------------- next part -------------- An

[LLVMdev] Benchmarks for small embedded platforms
Hi Everyone, As you may recall (I posted a while back) I'm currently doing a project measuring the energy consumption for different compiler flags. I've now gathered a set of benchmarks which I think are appropriate, for these (very) low end embedded platforms. The benchmarks that have been chosen: - CRC32, SHA - Prime sifting - Integer / floating point matrix multiplication - Cubic
