similar to: Speex for TI MSP430 microcontroller - estimating CPU speed requirements?

Interested in building a speex codec (basically audio <-> speex <-> data stream) using TI's small MSP430 microcontroller. Is there any way to estimate feasibility based on CPU requirements? Example - speex is happily encoding on an old Pentium-1 processor (166 MHz) using about half the CPU (as reported under Linux); the TI microcontrollers are much slower yet (8-16-25 MHz) and

Hi all, I'm rappedly moving away from windows, but one of the last programs i need to run in windows is 'IAR Embedded Workbench (Kickstart Version)' I've tried to run it some time ago (i think about 2 months back) in wine, but it didn't work so well back then. I haven't tried it with newer versions since then. I need that program so i can program my msp430

I have developed a flexible arithmetic coder implementation and I am now looking to incorporate it into a compression system for some proper testing. It is my intention to incorporate the coder into the Vorbis codec to attempt to improve on the current Huffman tree system. It would be useful if someone could point me at the main c and h files that deal with the entropy coding as I am currently

Dear all, I have been using Speex during last year over PC with very good results. Now I'm trying to move my code to the DSP TI C6713. It's the first time I work with a DSP and with Code Composer. I use speex quite well but I'm not very good at compiling for different platforms. After reading all manuals I tried to compile the speex library with Code Composer and the speex options for

I need capabilities, for my data analysis, like the Pinheiro & Bates S-Plus/R package nlme() but with binomial family and logit link. I need multiple crossed, possibly interacting fixed effects (age cohort of twin when entered study, sex of twin, sampling method used to acquire twin pair, and twin zygosity), a couple of random effects other than the cluster variable, and the ability to

Hello, Several people have expressed interest in using LLVM to target MSP430 microcontrollers. Anton wrote an MSP430 backend as an exercise, and some of the nastiest parts are done (thanks Anton!), but the consensus seems to be that there's still quite a bit of work left to do before LLVM can replace the commercial and open-source compilers (IAR, CCE, CrossWorks, mspgcc, and so on) that

Stripping out usused stuff is very easy, especially with static libraries. The only thing that could cause problem is the speed of the CPU. It's very hard to say what the requirements are because it depends a lot on the exact CPU you're using and (for ARM) the configuration of the cache and the speed of the bus.

Hi, I would like to compile the Speex fixed-point, WB decoder for an AT91SAM7S256 ARM7 microcontroller using gcc-arm-elf and was wondering, before I roll up my sleeves and try to figure out all the autoconf things that I'm really unfamiliar with, if anyone else has done this and can share their experiences. I see in the archives that some folk have compiled for this processor before but

Hello: I want to have a local telephone number that, when the people calls this number (via mobile or normal PSTN), the voip provider stablishes a SIP session to my asterisk box. It is possible? If yes... What providers have this service in Europe? It is difficult to configure and get things working ok? Will my asterisk box see the mobile or normal PSTN phone# that is calling the number

Well, the first question is whether you want encoding, decoding, or both. If there's one you don't need then you can remove that (unfortunately, there's no easy way right now). Even if you need both, then you can

Sounds like a job

Hi all, thanks a lot for your replies! Sorry for my typo, the flash size is 8MB (Byte) :-) Unfortunately I cannot use another flash because I'm working on a proprietary board. Jean-Marc, thanks for your suggestions. I thought to use fixed point for convenience, but I can work on floating point too, so I will take in account the codec2 (I didn't know it). Moreover, if you all have

Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.

When I did that on macOS, LDC generated a lot of complaints, possibly because it is assuming mach-o files. I tried changing from -mtriple=msp430

Hi everyone, inline asm code is like below: void test(unsigned short a) { asm("myinstr my16bitreg, %0"::"r"(a)); } I want it generate instruction "myinstr my16bitreg, r15" I execute llc test.bc -march = msp430 -o test.s then it reports "LLVM ERROR: Couldn't allocate input reg for constraint 'r' !" What's the reason?
