Serial port problem and strange solution (Fujitsu MCU development under wine)
Hi to everyone, this is my first post to the list. I'm developing an application for a Fujitsu MCU (90364 series) using Fujitsu Softune6 Workbench in linux under wine. Everithing works well exept for the firmware serial uploader. It starts and sends some commands to the MCU but hangs with a timeout error (obviously I've correctly simlinked and chmodded the appropriate ttyS*). To investiga...

Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU siz...

How to make opus work on a low end device ?
hi, I am porting opus encoder to a low end device with 32K ram, 256K flash and 32MHz arm M3 mcu. But opus seems consume too much. To make it work , what I can think of 1, Only fixed point supported 2, Only mono voice application supported 3, Set complexity to zero 4, Support only one sample rate, like 16KHz 5, Silk mode only or Celt mode only My question is , before I st...

No worries I’m very happy to provide any information necessary. I really want the port to accepted upstream. RL78 MCUs are part of the Renesas Product Longevity program https://www.renesas.com/eu/en/support/products-common/product-longevity-program-plp.html. The majority of current RL78 devices have the termination date set as “December 2033”, and a few “March 2026”. Also RL78 is under active development: new devi...

[LLVMdev] PIC16 removal details
I've been looking closely at LLVM as a means to developing a new toolchain for an MCU core of very similar architecture. To that end, the once included PIC16 backend might be a valuable reference. I found a message in April of this year that indicated it had been dropped from new releases however, and that were it to be resumed "it will be largely a rewrite". I'm wo...

Hello all, For the past couple of months I've been writing a new llvm backend for Renesas RL78 MCU: https://www.renesas.com/eu/en/products/microcontrollers-microprocessors/rl78.html The software manual which contains all there is to know about RL78 is available here: https://www.renesas.com/us/en/doc/products/mpumcu/doc/rl78/r01us0015ej0220_rl78.pdf The motivation behind this is the following:...

Speex on EFM32
Hi, Do you think that Speex could run in real time on the new EFM32 ultra-low consumption Cortex-M3 MCU (180 ?A/MHz) (NB 8KHz - Quality 4 - complexity 1 / same as STM32F103 Speex lib.) ? Its max speed is 32 MHz (about 40 MIPs). Thanks. Regards, Nicolas -------------- next part -------------- An HTML attachment was scrubbed...

opus library
Hello, I am interested in implementing opus decoder in my project. My OS: FreeRTOS MCU: NXP IMXRT1060 IAR 8.32 I integrated the library opus and successfully compiled (at least didn?t receive compile warning or errors). What a right way to take opus file and decode to wav file? I see, there a few examples, but I don?t know what example will be suitable for me? Pls advise, Kind...

[LLVMdev] Lowering Atomic Load to Acquire and Load
I'm working with an experimental backend for an MCU with heavy multithreading capabilities but lacks proper acquire/release semantics. This is okay, as the programmer can customize __cxa_guard_acquire and __cxa_guard_release to lower/raise appropriate semaphores. The issue I'm having is that I can't seem to figure out when to lower ato...

Speex on EFM32
On ST forums there is someone that states it has done an optimized port of the library that run Speex at 4Kbps (ST port is only 8Kbps).

opus library issues
Hello, I integrated the latest library 1.5.2 into my system. To compile the library have to allow VLA in IAR. Running FreeRTOS on MCU NXP IMXRT1060. I encoding the file using opus_demo.exe. And for decoding I took the part of opus_demo.c and implemented on my MCU. I experience a system crash from time to time by running the decoding. I don?t see any memory overflow not in heap, not thread overflow. Is there a situation that...

Swissvoice ip10: No 3-way-calling! (MGCP)
...---- As it turns out the 10S cannot conference on the device. From Jean-Francois at Swissvoice: Hi Mark, IP10S have not the capabilities to mix by itself 2 RTP flows, that why it refuses the conference mode. Most often, with the different partner we have, the conference capability is managed by a MCU on the network, then on the phone side, it's transparent. Regards, Jean-Francois If you want you can open a feature request that we be able to use a zap conference to implement three-way calling when unavailable on the end device, but that's a pretty good sized development project.

Asterisk: how to limit h323 connections.
...following rules in my dialplan: exten => 123,1,DIAL(H323/1100) exten => 234,1,DIAL(H323/2200) and I would like to limit to 5 the number of h323 connections for exten 123 e to 2 those for 234. The reason to limit the number of connectios is that these h323 connections are redirected to a MCU which accept all connections you put to, so I want to limit the number of connection that the MCU can accept for different extensions. There exist a simple way to do it? thx in advice! -- Alessandro R. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.d...
