[PATCH v5 0/33] MR9928: Draft: dsound: Speed up resampling.
by Anton Baskanov (＠baskanov) Feb. 7, 2026

Feb. 7, 2026

This implements a number of optimizations, in particular: - Swapping around the resampling loops in case of downsampling, allowing the FIR step to stay fixed regardless of the resampling ratio. - Rearranging the FIR array elements to make the access sequential. - Adding SSE versions of the resampling functions. Together, these amount to more than a 5x reduction of `cp_fields_resample` execution time. The quality of the resampling should be the same, or even improve slightly, due to a more precise `rem` calculation and removal of the FIR step rounding, although I haven't yet conducted any measurements. **UPDATE** Added some more optimizations: - Using fixed point math inside the resampling functions. - Optimizing the SSE versions by hand. - Adding AVX+FMA3 versions of the resampling functions. - Getting and putting all channel samples in one go. Combined with the previous ones, these bring the total speedup to 15x for upsampling and 13x for downsampling compared to the upstream. -- v5: dsound: Get all channel samples in one go. dsound: Put all channel samples in one go. dsound: Get rid of get_aux and call the functions directly. dsound: Get rid of put_aux and call the functions directly. dsound: Add a 32-bit AVX+FMA3 version of downsample. dsound: Add a 32-bit AVX+FMA3 version of upsample. dsound: Add a 32-bit SSE version of downsample. dsound: Add a 32-bit SSE version of upsample.
