Hi, I am working on performance tuning of opus library on ARMv5E platform. Our marvell soc also have wmmx simd coprocessor for speed optimization. Now, I have profiled quant_all_bands() function and it seems its taking almost 51% time of whole frame decoding. I have tried to find out the hot spots parts in this function and it seems quant_all_partition() function is taking too much time. Now I m trying to locate the main hotspot parts in this function but as this function...

Hi everyone, I have profiled Opus on AArch64. I just run opus_demo with some pcm files. Following is time proportion of FFT with different bitrate. Bitrate | Time cost by FFT/iFFT 24kb/s | 15% 48kb/s | 15% 96kb/s | 13% Any comment? I want some data close to real application, any suggestion?
