...oard (also a very expensive one) with a bit rate of 4800bps. When I found this project, I tought the vocoder hardware could be implemented based on the Speex code, since it works with similar bitrates. Is speex suitable for that? What are the main hindrances? I thought in using some high speed uController (code would be implemented in C and ASM), or a low cost FPGA (in wich the vocoder would be implemented in some hardware description language, such as VHDL); what do you thing about this? Thanks in advance. Wishing to hear from you soon, Andr? Melo Carvalhais Dutra.

...: ProcNoItin<"arm940t", [ArchV4T]>; def : ProcNoItin<"ep9312", [ArchV4T]>; I would like to understand if LLVM can be used for ArchV4T or not. Could you please indicate specific documentation for llvm ARM codegen? Does anybody use llvm with arm7tdmi ucontroller (e.g. at91sam7xxx) Thank you again for your help, pz 2010/1/10 Anton Korobeynikov <anton at korobeynikov.info>: > Hello, Pazzo > >> Any clue? > Yes.

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

...I'd share what I've learnt. It has a serial interface in the form of a RJ12 connector. Pinout: 1: GND 2: 3: 4: 5: Rx on Host 6: Tx on Host I think the other pins are used for simple level signals. Invalid commands are met with a "?" responce. >From the firmware in the PIC uController I've discovered the following commands (the "?" is part of the command): PTR NTR ENABLE COND? STATUS? MFG? STOP BATTEST BATTEST? EMOFF PN? SN? REV? Command meanings: Command: PTR Example Responce: Comment: Unknown, no reponce recieved Command: NTR Example Responce:...

...are with pipelines, unrolling loops, etc. At the moment most of the proprietary codecs with which I am familiar are targeted to the T.I. DSP's. That means that Analog Devices and ARM are "one down" competitively ... they desperately need a codec that's been optimized for their ucontrollers. I'll bet we could get some early support ... hardware, software, and maybe even $$ from them and I'd be willing to make the approach (can you say Blackfin from Analog Devices?). I think that mine is a particularly interesting proposition because the Embedded Systems Conference is c...

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

The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
