similar to: Query: Can i develope vorbis decoder on ARM processor

I don't know if this is the right place to ask but is there any timetable for thumb mode support on sub-ARMv6 processors? The exact processor support what i'm interested in is arm7tdmi. -Waltteri

Well, it's an ARM7TDMI core, so basically one register operation per clock, with memory accesses taking longer. Having the memory on-chip should make memory access much less of an impact. I was afraid that you would answer the way you did: I thought about my question after I sent it, and the "LP" in CELP is what makes it a sequential process; it can't do linear prediction on a

Hi, I study electricity in the University of Applied Sciences of Western Switzerland and I just began my diploma work: an embedded Internet Radio Receiver. I want to use the Tremor Codec on a ARM7TDMI uc (Samsung S3C4510B). And I need to convert the decoded Vorbis signal in an I2S bus signal (clk, word-select, and data) with a CPLD (Xilinx SPARTAN II) It will be helpfull if someone can explain

Dear ML, Anton, Thank you for your answer and your help. I had a look at ARM.td of LLVM 2.6 (in lib/Target/ARM..) where I found following definitions: // V4T Processors. def : ProcNoItin<"arm7tdmi", [ArchV4T]>; def : ProcNoItin<"arm7tdmi-s", [ArchV4T]>; def : ProcNoItin<"arm710t", [ArchV4T]>; def :

Dear Anton, Thank you again for your help! I tried with the following options (adding --with-cpu=arm7tdmi and using binutils from cvs snapshot): ../llvm-gcc4.2-2.6.source/configure --prefix=/usr/local/cross-llvm-gcc-arm-elf-4.2-2.6 --program-prefix=llvm- --enable-llvm=/Users/dummy/Develop/llvm/llvm-build --enable-languages=c,c++ --host=i686-apple-darwin9 --build=i686-apple-darwin9

Hello everyone, this is most likely Arm specific, but could affect other targets where there is a somewhat complex relationship between the triple and mcpu option. At present when clang is used as a linker driver for the gold-plugin and when using and an explicit -mcpu is not given to clang, then clang will always generate a -Wl,-plugin-opt=mcpu=<default CPU> where the default CPU is based

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

Hello, Pazzo > Any clue? Yes. Sorry, my fault - next time I should check ARM docs before replying. ARM7TDMI is ARMv4T and this is not supported by LLVM (LLVM does v5+ codegen). -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hello, I am interested to use Speex but need to know If I can use it under our project's constraint. We need to use a low cost micro controller on a very small PCB. This means there's no space for an external DSP unit. Can someone tell me if using an AVR32 (Atmel uc) which has a floating point calculation unit and DSP instruction set and running at ~50Mhz for a narrow band

Hello, Pazzo > I had a look to llvm (2.6) configure options but I couldn't find any > way to specify cpu type, fpu ecc.. These are not llvm configure options, but gcc's one. Basically, you should configure llvm-gcc in the same way you do for gcc for your platform. > Could you please give me any > indication and/or example? I want to try llvm with Atmel's > AT91SAM7X256

Dear Anton, Thanks for your help! I had a look to llvm (2.6) configure options but I couldn't find any way to specify cpu type, fpu ecc..Could you please give me any indication and/or example? I want to try llvm with Atmel's AT91SAM7X256 (core is ARM7TDMI ) Thank you again, pz 2010/1/9 Anton Korobeynikov <anton at korobeynikov.info>: > Hello > >> But I got the

Hello All. Could anybody help me with one question about CELT? I develop one project based on ARM7TDMI or Cortex C3 core. Can i use CELT with 32kHz and 48kB on these fixed point cores? Or it`s need to transfer project to Blackfin core (but it isn`t convenient to me)? With best regards, Alexey Voroshen.

I have to define a project that will have speex in the future. Can someone give me information about Speex running on an ARM7TDMI(v4) such as AT91SAM7S64? I will expect to use AEC, AGC noise reduction, encode and decode. Is this supposed to run? Or do I need something faster or different? Just for information: the chip runs at 55MHz, 1 wait stat in 32 bit mode or 0 wait in thumb mode. I

Hello, I may be stupid, but I cannot find any data on how "expensive" the Vorbis Decoder is. Looking for an embedded solution I am interested in how many "MIPS" you need to decode a MONO audio stream at reasonable quality (44 kHz, approx. 100 kbps?) Can it be done in a microcontroller, or do I need ultra-expensive DSPs to do it? Thanks for hints Jens --- >8 ---- List

Hello, I'm sorry if this is not the correct place to ask this question but what I'm looking for is any data on the reality of Speex working on an ARM7 core? I'm looking at doing a few diffrent projects where I will be using a proc such as the LPC2378 with the ARM7TDMI-S core running at 72Mhz (although errata show only 60Mhz is currenlty possible). Do you know if there is a port

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 am porting speex on ARM7TDMI, I have done some optimization, the result is that the encoder and decoder need about 60 MCPS for 5.96kbps bitrate and complexity 0. Can someone give me informtion about Speex optimization on ARM7? Another question, my ADC and DAC are 12 bits, but Speex codec is 16bits, Did someone try to modify speex to 12 bits? I think if I modify speex to 12 bits, the

Hello, I'm trying to do the following and encountering problems with the generated arm assembly code: I've got an application in two parts that i've compiled into llvm bitcode using: llvm-gcc -emit-llvm -c part1.c -o part1.bc llvm-gcc -emit-llvm -c part2.c -o part2.bc Then I link them together: llvm-ld part1.bc part2.bc -o combined.bc Now I use the ARM backend via llc to

Well how about as a strawman... taking some options from http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores and http://en.wikipedia.org/wiki/List_of_applications_of_ARM_cores LLVM Supports: ARMv4T -> ARM7TDMI ARMv5TE -> ARM926EJ-S -> XScale ARMv6 -> ARM1136J(F)-S ARMv6ZK -> ARM1176JZ(F)-S ARMv7A -> Cortex-A8 Cortex-A9 ARMv7M -> Cortex-M3
