RNN VAD: use `VectorMath::DotProduct()` for pitch search This CL brings a large improvement to the RNN VAD CPU performance by finally using `VectorMath::DotProduct()` for pitch search. The realtime factor improved from about 390x to 570x for SSE2 (+180x, 45% faster) and to 610x for AVX2 (+235x, 60% faster). RNN VAD benchmark results: ``` +-----+-------+------+------+ | run | none* | SSE2 | AVX2 | +-----+-------+------+------+ | 1 | 393x | 572x | 618x | | 2 | 388x | 568x | 607x | | 3 | 393x | 564x | 599x | +-----+-------+------+------+ ``` *: baseline, no SIMD used for pitch search, but SSE2 used for the RNN Results obtained as follows: 1. Force SSE2 in `DISABLED_RnnVadPerformance` for the RNN part in order to measure the baseline correctly: ``` RnnBasedVad rnn_vad({/*sse2=*/true, /*avx2=*/true, /*neon=*/false}); ``` 2. Run the test: ``` $ ./out/release/modules_unittests \ --gtest_filter=*RnnVadTest*DISABLED_RnnVadPerformance* \ --gtest_also_run_disabled_tests --logs ``` Bug: webrtc:10480 Change-Id: I89a2bd420265540026944b9c0f1fdd4bfda7f475 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/195001 Reviewed-by: Gustaf Ullberg <gustaf@webrtc.org> Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32755}
WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
See here for instructions on how to get started developing with the native code.
