## SMINP

Signed minimum pairwise.

Compute the minimum value of each pair of adjacent signed integer elements within each source vector, and interleave the results from corresponding lanes. The interleaved result values are destructively placed in the first source vector.

### Assembler Symbols

 Is the name of the first source and destination scalable vector register, encoded in the "Zdn" field.
<T> Is the size specifier, encoded in size:
size <T>
00 B
01 H
10 S
11 D
 Is the name of the governing scalable predicate register P0-P7, encoded in the "Pg" field.
 Is the name of the second source scalable vector register, encoded in the "Zm" field.

### Operation

```CheckSVEEnabled();
integer elements = VL DIV esize;
bits(VL) operand1 = Z[dn];
bits(VL) operand2 = Z[m];
bits(VL) result;
integer element1;
integer element2;

for e = 0 to elements-1
if ElemP[mask, e, esize] == '0' then
Elem[result, e, esize] = Elem[operand1, e, esize];
else
if IsEven(e) then
element1 = SInt(Elem[operand1, e + 0, esize]);
element2 = SInt(Elem[operand1, e + 1, esize]);
else
element1 = SInt(Elem[operand2, e - 1, esize]);
element2 = SInt(Elem[operand2, e + 0, esize]);
integer res = Min(element1, element2);
Elem[result, e, esize] = res<esize-1:0>;

Z[dn] = result;```

### Operational information

If PSTATE.DIT is 1:

• The execution time of this instruction is independent of:
• The values of the data supplied in any of its operand registers when its governing predicate register contains the same value for each execution.
• The values of the NZCV flags.
• The response of this instruction to asynchronous exceptions does not vary based on:
• The values of the data supplied in any of its operand registers when its governing predicate register contains the same value for each execution.
• The values of the NZCV flags.

This instruction might be immediately preceded in program order by a MOVPRFX instruction. The MOVPRFX instruction must conform to all of the following requirements, otherwise the behavior of the MOVPRFX and this instruction is unpredictable:

• The MOVPRFX instruction must be unpredicated.
• The MOVPRFX instruction must specify the same destination register as this instruction.
• The destination register must not refer to architectural register state referenced by any other source operand register of this instruction.
