Paul E. Murphy	33fb253a66	core: vectorize dotProd_32s Use 4x FMA chains to sum on SIMD 128 FP64 targets. On x86 this showed about 1.4x improvement. For PPC, do a full multiply (32x32->64b), convert to DP then accumulate. This may be slightly less precise for some inputs. But is 1.5x faster than the above which is about 1.5x than the FMA above for ~2.5x speedup.	6 years ago

Hugo Lindström	935067ee05	Merge pull request #15265 from hugolm84:wince-armv7-supports-neon * WINCE 8.0 requires ARMv7 Thumb2 and thus have NEON instructions * Only add NEON if on _ARM_	6 years ago
Chip Kerchner	d513fb4c8e	Merge pull request #15199 from ChipKerchner:hogToHal Convert HOG from SSE SIMD to HAL - 35-45% faster on Power (VSX) (#15199) * Convert SSE SIMD to HAL. 35-45% improvement for Power (VSX) * Remove CV_NEON code. Use v_floor instead of 3 lines of code. * Invert comparison logic to simplify code. * Change initialization from v_load to constructor type.	6 years ago
Jake Howard	76b40a37e7	Merge pull request #15111 from RealOrangeOne:patch-1 * Remove unavoidable print of CV error The return value covers whether the device exists. This might be better hidden behind a debug flag, but I couldn't work out how to do that nicely. * Use `CV_LOG_WARNING` macro to log rather than removing it entirely	6 years ago

Paul E. Murphy	f38a61c66d	fast_math: implement optimized PPC routines Implement cvRound using inline asm. No compiler support exists today to properly optimize this. This results in about a 4x speedup over the default rounding. Likewise, simplify the growing number of rounding function overloads. For P9 enabled targets, utilize the classification testing instruction to test for Inf/Nan values. Operation speedup is about 1.2x for FP32, and 1.5x for FP64 operands. For P8 targets, fallback to the GCC nan inline. It provides a 1.1/1.4x improvement for FP32/FP64 arguments.	6 years ago
Paul E. Murphy	3f92bcc11a	fast_math: selectively use GCC rounding builtins when available Add a new macro definition OPENCV_USE_FASTMATH_GCC_BUILTINS to enable usage of GCC inline math functions, if available and requested by the user. Likewise, enable it for POWER. This is nearly always a substantial improvement over using integer manipulation as most operations can be done in several instructions with no branching. The result is a 1.5-1.8x speedup in the ceil/floor operations. 1. As tested with AT 12.0-1 (GCC 8.3.1) compiler on P9 LE.	6 years ago
Paul E. Murphy	b2135be594	fast_math: add extra perf/unit tests Add a basic sanity test to verify the rounding functions work as expected. Likewise, extend the rounding performance test to cover the additional float -> int fast math functions.	6 years ago
