Converts packed double precision floating-point values in the source operand (second operand) to packed unsigned quadword integers in the destination operand (first operand).
When a conversion is inexact, the value returned is rounded according to the rounding control bits in the MXCSR register or the embedded rounding control bits. If a converted result cannot be represented in the destination format, the floating-point invalid exception is raised, and if this exception is masked, the integer value 2w – 1 is returned, where w represents the number of bits in the destination format.
The source operand is a ZMM/YMM/XMM register or a 512/256/128-bit memory location. The destination operation is a ZMM/YMM/XMM register conditionally updated with writemask k1.
EVEX.vvvv is reserved and must be 1111b otherwise instructions will #UD.
