| Parameter | Description |
|---|---|
| a | Vector a |
| b | Vector b |
| imm8 | Control mask |
v256 Vector
Blend packed double-precision (64-bit) floating-point elements from a and b using control mask imm8, and store the results in dst.
____ VBLENDPD ymm1, ymm2, ymm3/v256, imm8 Double-Precision Floating-Point values from the second source operand are conditionally merged with values from the first source operand and written to the destination. The immediate bits [3:0] determine whether the corresponding Double-Precision Floating Point value in the destination is copied from the second source or first source. If a bit in the mask, corresponding to a word, is "1", then the Double-Precision Floating-Point value in the second source operand is copied, else the value in the first source operand is copied
