MOVT (table to scalar)

Move 8 bytes from ZT0 to general-purpose register

This instruction moves 8 bytes to a general-purpose register from the ZT0 register at the byte offset specified by the immediate index. This instruction is UNDEFINED in Non-debug state.

Encoding: SME2

Variants: FEAT_SME2 (ARMv9.3)

MOVT <Xt>, ZT0[<offs>]

Decoding algorithm

if !IsFeatureImplemented(FEAT_SME2) || !Halted() then EndOfDecode(Decode_UNDEF);
constant integer t = UInt(Rt);
constant integer offset = UInt(off3);

Operation

CheckSMEEnabled();
CheckSMEZT0Enabled();
constant bits(512) operand = ZT0[512];

X[t, 64] = Elem[operand, offset, 64];

Explanations

<Xt>: Is the 64-bit name of the general-purpose register to be transferred, encoded in the "Rt" field.
<offs>: Is the immediate byte offset, a multiple of 8 in the range of 0 to 56, encoded in the "off3" field as <offs>/8.
