similar to: How many MIPS for Vorbis Decoder?

Hi All, Currently I am investigating how interesting OGG is for me. The most important requirements are: - Decoding on embedded hardware, ARM7 or ARM9. - Mixing multiple audio streams/files on embedded hardware First of all how difficult is it to decode OGG on an ARM7/9 processor? I read that OGG decoding needs floating point support? Secondly I would like to know how many MIPS are needed to

Hi all, I'm very new to Ogg, and am learning about it in an attempt to stream it from a CF card through a microcontroller. This particular setup requires me to move parts of the file from the CF card to the microcontroller buffer, effectively making the file like a data stream. Also, should this question be directed at the Tremor group instead since that is the codec I'm using? It

Hi, Tis is kiran. I ve a project in which v have to cross compile the source code of ogg vorbis audio decoder onto EDB9302 ARM board.. Can u pls tell me the steps how to proceed or lead me to a source whr i can find the procedure... Thank u -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi people, I am aware of the integer based DEcoder (Tremor) but am more interested in a hardware ENcoder, for use in a solid state portable recorder. Has anyone made *any* steps towards implementing an encoder in a DSP? I ask because I have been investigating MP3 hardware encoders, and apart from being very expensive (to licence - DSPs are as cheap as grains of sand in comparison) I have an

Hi, I'm a Pocket PC developer and have created a audio translator application on this platform. I currently make use of an MP3 decoder engine, but due to heavy licensing fees I'm thinking of switching over to a patent free format. Vorbis presents the best approach. I read that tremor decoder has been especially optimized for embedded devices. I'd like to make use of this and

Hi all: I am a newbie to vorbis, and I want to develop vorbis decoder onto TI c6701 evm board. And I try the tremor code and libvorbis and the code from http://www.xiph.org/archives/tremor/200210/0001.html . But all of them stll work good in MSVC but terrible in c6701. I dont know wher the problem is??Problem of code or problem of memory allocation?? it decodes almost noise,.... When I

Hello, I'm currently evaluating different codecs to create a list of candidates for my current project. My criteria are simple: - What is the expected highest compression ratio where no noticeable degradation occurs yet? I need something like 1/8th compared with wave data. - Is it possible to access the decoded streams for further processing outside of the codec? If yes, can the data be

Hi All, I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. I have following doubts: 1) What is min and max bitrate? 2)What is max Audio Packet size ? 3)What is the max size of setup header? 4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 5) What window sizes in Ogg Vorbis are normally

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.

As to tremor fixed-point implementation, i got several questions, and hopefully some one can help me out. Thanks a lot! 1. For DSP chips with small and limited memory, how much memory do we really need for saving all codebooks before we start to decode audio packets? Can the bit-rate give us some clues? Is there some simple guidelines for this? 2. For CRC error protection, it seems to me that

Hello, Iam interesting in transcoding the algorithm of OGG VORBIs in fixed point because I have to implemente this encoder in a fixed point DSP. Does the source code of ogg vorbis encoder exist in fixed point or is there people that work on this or anything else?

This was also our experience porting the Tremor vorbis decoder to a TI dsp. The vendor toolchain is useless; someone really needs to pay cygnus to port gcc. -r ---

Hi Everyone, Has anyone had any experience of using the Promise FastTrak SX4000 or SuperTrak SX6000 IDE RAID Controllers under Centos (if it matters I'm using version 4). I've seen it listed on linuxcompatible.org as working but would prefer to find out any first-hand experince before I buy. I'm looking to build a new mini server based on Mini-ITX and have found a great 1U case

We've made a little change that changed the output of vorbis is there a way to check the accuracy of the output against the original output? I also asked this question in the irc ... Thanks, Tal.

I'm not sure how you get a 7% overhead. In most uses I've seen, the overhead is more around 1%. > At the same time the > file

What is wrong with running the C code on a DSP? Sure you can improve the efficiency if you use assembly, but why do you say it is *necessary*? Regards, Steve --- >8

Hi everyone, I'm looking into setting up a SATA hardware raid, probably 5 to use with CentOS 4. I chose hardware raid over software mostly because I like the fact that the raid is transparent to the OS. Does anyone know of any SATA controllers that are well tested for this sort of usage? From what I can tell from googling, this is more or less where RHEL stands: Red Hat Enterprise Linux

Sorry for an OT post, but given the recent discussions here re raid, I was wondering if anyone had any info on the ITE 8212 RAID controller (GigaRAID) This is a PATA HW RAID as found on the GigaByte GA-8I915P-PRO motherboard. (I can see an IC on the board labeled GigaRAID. Their manual claims that is has it's own CPU). I am not using it because I have SATA, but I am still curious about

I am interested in using Speex in an embedded system built around an ARM microcontroller. I have seen other posts indicating that Speex can run in real-time on some iPAQ PDA's, but these are using a StrongARM 166MHz processor. I'm looking more at the chips from Atmel (SAM7), Philips (LPC2xxx), and TI (TMS 470), which are ARM7TDMI with on-chip SRAM and flash, running at speeds of 33 to
