• 493800a0f3 Fix NEON widening code to avoid using vsubl_u8 (which returns uint16x8_t) and instead zero-extend with vmovl_u8, reinterpret to int16x8_t, then subtract 127 with vsubq_s16. This should fix the type mismatch and produce correct signed results. Moved use_avx2, use_sse2, and use_ssse3 declarations inside the #if defined(__x86_64__) || defined(__i386__) block. arancormonk 2025-09-05 18:21:57 -05:00

• 5834127ff7 rtl_sdr_fm: fix rotate+widen tail handling (scalar/AVX2/NEON) to preserve 90° rotation and add SSSE3 rotate+widen with runtime dispatch on x86. Also include tmmintrin and clarify SSE2 fallback comment. arancormonk 2025-09-03 22:33:32 -05:00
• 2ce089ccf8 rtl_sdr_fm: make SIMD runtime dispatch thread-safe with pthread_once and ensure AVX2/SSE2 paths compile by relying on function-level target attributes (remove AVX2/SSE2 guards).

• 4e64ef1c11 rtl_sdr_fm: add runtime SIMD dispatch for widen/rotate paths, selecting AVX2/SSE2/NEON via CPUID/XGETBV (x86) or getauxval (ARM) with scalar fallbacks. Replace compile-time guards with lazy-initialized function-pointer wrappers so binaries run optimally across CPUs without changing call sites. arancormonk 2025-09-03 22:06:55 -05:00
• c764cf0eda rtl_sdr_fm: replace USB→demod double-buffer/condvar handoff with a lock-free SPSC ring; enqueue widened blocks and drop oldest on overflow to keep the callback non-blocking.

• 8b4fa81711 rtl_sdr_fm: consume HB cascade output in-place to avoid the final memcpy. Track the current buffer and assign lowpassed to the last stage’s output, preserving correctness while reducing memory traffic. arancormonk 2025-09-03 21:38:50 -05:00
• 106aae1814 rtl_sdr_fm: fuse interleaved complex half-band decimation to avoid deinterleave/reinterleave in full_demod, reducing memory traffic and copies. Maintain per‑stage histories and equivalent output while improving throughput. arancormonk 2025-09-03 21:35:34 -05:00
• 391048a45a rtl_sdr_fm: vectorize rotate+widen path: add AVX2/NEON implementations for widen_rotate90_u8_to_s16_bias127 with scalar tail fallback. This applies the 90° rotation and bias-127 widening in vectors to reduce callback CPU without changing behavior. arancormonk 2025-09-03 21:23:05 -05:00
• 1b9c3aa659 rtl_sdr_fm: add residual-CFO FLL and optional Gardner timing correction before discriminator (TED disabled by default and applied only to non-FM unless forced), with linear interpolation, nominal 1/sps advance, and env-tunable gains. arancormonk 2025-09-03 21:18:20 -05:00
• e9b12b8bc6 rtl_sdr_fm: add polyphase rational resampler (L/M) enabled by default at 48 kHz (override via DSD_FME_RESAMP), integrate post-demod and update output.rate while keeping legacy upsampler as fallback. Implement tap design with L-phase gain compensation. arancormonk 2025-09-03 21:02:19 -05:00
• 9e9ae95219 rtl_sdr_fm: use fast atan2 discriminator for analog mode to reduce quantization noise arancormonk 2025-09-03 20:33:04 -05:00
• 86d91512bb rtl_sdr_fm: add AVX2 widening, optional combined rotate+widen, and fixed‑point linear upsampler with env flags; preserve legacy behavior by default. Fix decoding by matching legacy upsample length (NM) with tail fill and reproducing unsigned rotate semantics. arancormonk 2025-09-03 20:20:41 -05:00
• 0b00832b1f rtl_sdr_fm: enable env-gated intra-block multithreading with a tiny 2-thread pool and preallocated buffers. Parallelize HB I/Q decimation and linear upsampler; add debug log when enabled. arancormonk 2025-09-03 19:52:06 -05:00
