Floating Point Dot Product Intrinsics
These Intel® Streaming SIMD Extensions (Intel® SSE4) intrinsics enable floating point single-precision and double-precision dot products. The prototypes for these intrinsics are in the
To use these intrinsics, include the
immintrin.hfile as follows:
Corresponding Intel® SSE4 Instruction
Double-precision dot product
Single-precision dot product
Calculates the dot product of double-precision packed values with mask-defined summing and zeroing of the parts of the result.
