VPBROADCASTD

Broadcasts a dword-size value from a memory location or a YMM register to all 32-bit lanes of the destination YMM or ZMM register.

The following table covers what the source and destinations can be.

DO NOT support LOCK

This instruction requires AVX or AVX2 support. It is only available in 64-bit mode or compatibility mode when executing 64-bit code.

When the destination is a ZMM register and the source is a YMM register, the dword value is broadcast to all 8 lanes of the ZMM register. If the destination is a YMM register and the source is a ZMM register, the value is broadcast from the lowest 32 bits of the source ZMM register to the 4 lanes of the YMM register. Using a ZMM register as a destination with a YMM source results in the upper 128 bits of the source being ignored.
