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.	5 years ago

Alexander Alekhin	5ef548a985	cmake: update initialization	5 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.	5 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.	5 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.	5 years ago

Stefan Brüns	e9a2e665b2	Explicitly default operator= for Vec<T, n> Due to the explicitly declared copy constructor Vec<T, n>::Vec(Vec <T,n>&) GCC 9 warns if there is no assignment operator, as having one typically requires the other (rule-of-three, constructor/desctructor/assginment). As the values are just a plain array the default assignment operator does the right thing. Tell the compiler explicitly to default it.
