Description
Thanks for the open source!
I tried to use the OPUS compression algorithm on STM32L476@80Mhz, compressing 12K, 40ms, 480 data, -Of optimization, complexity 1, it took 25ms, and then defined OPUS_ARM_ASM, OPUS_ARM_INLINE_ASM two definitions, but the speed did not improve, there is Any other way to increase the speed? Thank you

Research direction
Start by reproducing the reported 25 ms compression time on the STM32L476 at 80 MHz with 12K, 40 ms, 480-sample data, complexity 1, and the stated optimization settings. Compare the results with and without OPUS_ARM_ASM and OPUS_ARM_INLINE_ASM; done means identifying a verified speed improvement or documenting why the definitions do not help.
