speculable  exu stream  exu block  compute phase   operation   in the logical value domain  

native on: all

Duplicate a scalar value into a vector.

The number of vector elements depends on the width of the scalar and the Core dependent vector width of operands.

related operations: mask

splat(op op0, width width0) → op r0

operands: like Splat xx:X


Core In Slots Latencies
Tin E0
