ADDQP

Add pairwise within quadword vector segments (unpredicated)

This instruction adds pairs of adjacent elements within each concatenated pair of 128-bit segments of the first and second source vectors, and places the results in the corresponding 128-bit segment of the destination vector.

This instruction is unpredicated.

Encoding

ADDQP <Zd>.<T>, <Zn>.<T>, <Zm>.<T>

Decode for this encoding

if !IsFeatureImplemented(FEAT_SVE2p3) && !IsFeatureImplemented(FEAT_SME2p3) then EndOfDecode(Decode_UNDEF); end; let esize : integer{} = 8 << UInt(size); let n : integer = UInt(Zn); let m : integer = UInt(Zm); let d : integer = UInt(Zd);

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T>

Is the size specifier, encoded in size:

size <T>
00 B
01 H
10 S
11 D
<Zn>

Is the name of the first source scalable vector register, encoded in the "Zn" field.

<Zm>

Is the name of the second source scalable vector register, encoded in the "Zm" field.

Operational information

This instruction is a data-independent-time instruction as described in About PSTATE.DIT.
