Description

FMA intrinsics

Static Properties

Property Description
IsFmaSupported Evaluates to true at compile time if FMA intrinsics are supported. Burst ties FMA support to AVX2 support to simplify feature sets to support.

Static Methods

Method Description
fmadd_pd Multiply packed double-precision (64-bit) floating-point elements in a and b, add the intermediate result to packed elements in c, and store the results in dst.
fmadd_ps Multiply packed single-precision (32-bit) floating-point elements in a and b, add the intermediate result to packed elements in c, and store the results in dst.
fmadd_sd Multiply the lower double-precision (64-bit) floating-point elements in a and b, and add the intermediate result to the lower element in c. Store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.
fmadd_ss Multiply the lower single-precision (32-bit) floating-point elements in a and b, and add the intermediate result to the lower element in c. Store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst.
fmaddsub_pd Multiply packed double-precision (64-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst.
fmaddsub_ps Multiply packed single-precision (32-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst.
fmsub_pd Multiply packed double-precision (64-bit) floating-point elements in a and b, subtract packed elements in c from the intermediate result, and store the results in dst.
fmsub_ps Multiply packed single-precision (32-bit) floating-point elements in a and b, subtract packed elements in c from the intermediate result, and store the results in dst.
fmsub_sd Multiply the lower double-precision(64-bit) floating-point elements in a and b, and subtract the lower element in c from the intermediate result.Store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.
fmsub_ss Multiply the lower single-precision (32-bit) floating-point elements in a and b, and subtract the lower element in c from the intermediate result. Store the result in the lower element of dst, and copy the upper 3 packed elements from a to the upper elements of dst.
fmsubadd_pd Multiply packed double-precision (64-bit) floating-point elements in a and b, alternatively subtract and add packed elements in c to/from the intermediate result, and store the results in dst.
