ZERO (single-vector)

Zero ZA single-vector groups

This instruction zeroes two or four ZA single-vector groups.

The single-vector group within each half of or each quarter of the ZA array is selected by the sum of the vector select register and offset, modulo half or quarter the number of ZA array vectors.

The vector group symbol, VGx2 or VGx4, indicates that the ZA operand consists of two or four ZA single-vector groups respectively.

It has encodings from 2 classes: Two ZA single-vectors and Four ZA single-vectors

Two ZA single-vectors
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); end; let v : integer = UInt('010'::Rv); let offset : integer = UInt(off3); let ngrp : integer = 2;

Four ZA single-vectors
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); end; let v : integer = UInt('010'::Rv); let offset : integer = UInt(off3); let ngrp : integer = 4;
