VSHR (by immediate)
Vector Shift Right by immediate value.
Syntax
VSHR
{

{datatype
}, Qd
, #Qm
imm
VSHR
{
}.cond
{datatype
}, Dd
, #Dm
imm
where:
cond
is an optional condition code.
datatype
must be one of
S8
,S16
,S32
,S64
,U8
,U16
,U32
, orU64
.Qd
,Qm
are the destination vector and the operand vector, for a quadword operation.
Dd
,Dm
are the destination vector and the operand vector, for a doubleword operation.
imm
is the immediate value specifying the size of the shift. The ranges are shown in the following table:
Table 14-22 Available immediate ranges in VSHR (by immediate)
datatype imm range or U8 0 to 8 S16 or U16 0 to 16 S32 or U32 0 to 32 S64 or U64 0 to 64 VSHR
with an immediate value of zero is a pseudo-instruction forVORR
.
Operation
VSHR
takes each element in a vector, right shifts them by an immediate
value, and places the results in the destination vector. The results are truncated.
