Syntax
VSRI{condsizeQdQmimm
VSRI{condsizeDdDmimm
where:
condis an optional condition code.
sizemust be one of
8,16,32, or64.Qd,Qmare the destination vector and the operand vector, for a quadword operation.
Dd,Dmare the destination vector and the operand vector, for a doubleword operation.
immis the immediate value specifying the size of the shift, in the range 1 to
size
Operation
VSRI takes each element in a vector, right shifts them by an immediate
value, and inserts the results in the destination vector. Bits shifted out of the right of
each element are lost. The following figure shows the operation of VSRI
with a single element and a shift value of two. The two most significant bits in the
destination vector are unchanged.
