HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to log2_frac().Shouldn't the line cwrs.c:313:ALLOC(u,K...

The attached code implements PVQ encoding/decoding with separated signs [1]. It's in Python to use the unlimited-precision integers. The concept is to map vectors on some L-dimensional pyramid into integers 0...N, just like the standard PVQ. The only change is the mapping itself. The mapping is altered so that all sign data is in the least significant bits. A vector with Z nonzero

Jean-Mark, Tim, Could either of you expound on the following comment in cwrs.c? /*If _k==0, the following do-while loop will overflow the buffer.*/ ---------------------------------------------------------------- ...because the following do-loop does overflow the buffer when k=126 k=2; do _u[k]=(k<<1)-1; while(++k<len); Thanks, MikeH...

Changes from RFC PATCH v3 - Just rebased on tip - For all else, please see notes from RFC PATCH v3 at http://lists.xiph.org/pipermail/opus/2015-March/002902.html - latest wip opus tree/branch https://git.linaro.org/people/viswanath.puttagunta/Ne10.git branch: rfcv4_final_fft_ne10 Viswanath Puttagunta (1): armv7(float): Optimize encode usecase using NE10 library Makefile.am

Changes from RFC PATCH v1: - passing arch parameter explicitly - reduced stack usage by ~3.5K by using scaled NE10 fft version - moved all optimization array functions to arm_celt_map.c - Other cleanups pointed out by Timothy Phil, As you mentioned earlier, could you please address all compile and linker errors/warnings coming out of Ne10 library? You can find my working Ne10 repo at [1] You

Changes from RFC PATCH v2 - fixed compile issue when just compiling for --enable-intrinsics for ARMv7 without NE10 - Notes for NE10: - All compile/link warnings are now in upstream NE10 - Only patch pending upstream in NE10 is the one that needs to add -funsafe-math-optimizations for ARMv7 targets. - Phil Wang @ ARM is working on getting this fixed. - Note that even without

Hello opus-dev, I've been cooking up this patchset to integrate NE10 library into opus. Current patchset focuses on encode use case mainly effecting performance of clt_mdct_forward() and opus_fft() (for float only) Glad to report the following on Encode use case: (Measured on my Beaglebone Black Cortex-A8 board) - Performance improvement for encode use case ~= 12.34% (Based on time -p
