Mradul Agrawal	640f188ca2	Merge pull request #19583 from theroyalpekka:patch-1 * Update polynom_solver.cpp This pull request is in the response to Issue #19526. I have fixed the problem with the cube root calculation of 2R. The Issue was in the usage of pow function with negative values of R, but if it is calculated for only positive values of R then changing x0 according to the parity of R, the Issue is resolved. Kindly consider it, Thanks! add cv::cubeRoot(double) Co-authored-by: Alexander Alekhin <alexander.a.alekhin@gmail.com>	2021-03-05 13:55:52 +00:00

On Armv8 in AArch64 execution mode, we can skip the sequence v<op>_<ty>(vget_high_<ty>(x), vget_high_<ty>(y)) in favour of v<op>_high_<ty>(x, y) This has better changes for recent compilers to use less data movement operations and better register allocation.

Clement Courbet	da555a2c9b	Optimize opencv dft by vectorizing radix2 and radix3. This is useful for non power-of-two sizes when WITH_IPP is not an option. This shows consistent improvement over openCV benchmarks, and we measure even larger improvements on our internal workloads. For example, for 320x480, `32FC`, we can see a ~5% improvement}, as `320=2^65` and `480=2^535`, so the improved radix3 version is used. `64FC*` is flat as expected, as we do not specialize the functors for `double` in this change. ``` dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, false) 1.239 1.153 1.07 dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, true) 0.991

Paul Murphy	a011035ed6	Merge pull request #15257 from pmur:resize * resize: HResizeLinear reduce duplicate work There appears to be a 2x unroll of the HResizeLinear against k, however the k value is only incremented by 1 during the unroll. This results in k - 1 duplicate passes when k > 1. Likewise, the final pass may not respect the work done by the vector loop. Start it with the offset returned by the vector op if implemented. Note, no vector ops are implemented today. The performance is most noticable on a linear downscale. A set of performance tests are added to characterize this. The performance improvement is 10-50% depending on the scaling. * imgproc: vectorize HResizeLinear Performance is mostly gated by the gather operations for x inputs. Likewise, provide a 2x unroll against k, this reduces the number of alpha gathers by 1/2 for larger k. While not a 4x improvement, it still performs substantially better under P9 for a 1.4x improvement. P8 baseline is 1.05-1.10x due to reduced VSX instruction set. For float types, this results in a more modest 1.2x improvement. * Update U8 processing for non-bitexact linear resize * core: hal: vsx: improve v_load_expand_q With a little help, we can do this quickly without gprs on all VSX enabled targets. * resize: Fix cn == 3 step per feedback Per feedback, ensure we don't overrun. This was caught via the failure observed in Test_TensorFlow.inception_accuracy.	2019-12-09 14:54:06 +03:00

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.	2019-08-20 15:28:36 -05:00

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.	2019-08-07 15:01:18 -05:00
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.	2019-08-07 15:01:18 -05:00
