Hi: currently, I am doing opus optimizing work on cortex-M4F(MT2523D), but it has little improvement, hope anyone can sync the work with me .

The patch prevents KEIL MDK compile warnings, like:   warning:  #1035-d: single-precision operand implicitly converted to double-precision Actually ARM Cortex-M4F has only a *single precision* (float) FPU. It's suit for all platforms. See the comment at the begin of patch file. Sincerely Forrest Zhang -------------- next part -------------- Specify the floating point constant with single precision. The patch changes the similar line A to B. A: if (ana...

Does a comprehensive set of instructions on how to compile Libvirt on a Microsoft Vista platform exist? Has this ever been accomplished? I would very much appreciate input from persons who can give me confidence that a Windows client application can be developed on top of Libviet that connects to a QEMU system on an Ubuntu server.

Hi, I would like to use OPUS codec to compress and decompress an audio stream for full-duplex intercom application; I would like to use a microcontroller equipped with Cortex-M4 core without NEON running at 72MHz. Does the OPUS codec works fine on that architecture? Do you have some benchmark data? Thank you in advance. Best regards. Daniele -------------- next part -------------- An HTML

Hi all ! I just learned about the Opus codec and would like to try it out on my NRF52 (Cortex-M4) target.   I've been struggling a bit with the "trival_example.c" setup but repeatedly run into "hard fault" crashes when stepping through the code. Firstly; for a "bare bone" configuration, does the following compiler directives make sense ? UDEFS =
