MOVA (tile to vector)

The instruction operates on individual horizontal or vertical slices within a named ZA tile of the specified element size. The slice number within the tile is selected by the sum of the slice index register and an immediate, modulo the number of such elements in a Streaming SVE vector. The immediate is in the range 0 to the number of elements in a 128-bit vector segment minus 1.

8-bit

if !HaveSME() then UNDEFINED; integer g = UInt(Pg); integer s = UInt('011':Rs); integer n = 0; integer imm = UInt(imm4); integer esize = 8; integer d = UInt(Zd); boolean vertical = V == '1';

16-bit
(FEAT_SME)

if !HaveSME() then UNDEFINED; integer g = UInt(Pg); integer s = UInt('011':Rs); integer n = UInt(ZAn); integer imm = UInt(imm3); integer esize = 16; integer d = UInt(Zd); boolean vertical = V == '1';

32-bit
(FEAT_SME)

if !HaveSME() then UNDEFINED; integer g = UInt(Pg); integer s = UInt('011':Rs); integer n = UInt(ZAn); integer imm = UInt(imm2); integer esize = 32; integer d = UInt(Zd); boolean vertical = V == '1';

64-bit
(FEAT_SME)

if !HaveSME() then UNDEFINED; integer g = UInt(Pg); integer s = UInt('011':Rs); integer n = UInt(ZAn); integer imm = UInt(i1); integer esize = 64; integer d = UInt(Zd); boolean vertical = V == '1';

128-bit
(FEAT_SME)

if !HaveSME() then UNDEFINED; integer g = UInt(Pg); integer s = UInt('011':Rs); integer n = UInt(ZAn); integer imm = 0; integer esize = 128; integer d = UInt(Zd); boolean vertical = V == '1';

Assembler Symbols

Operation

CheckStreamingSVEAndZAEnabled(); integer dim = VL DIV esize; bits(PL) mask = P[g]; bits(32) index = X[s]; integer slice = (UInt(index) + imm) MOD dim; bits(VL) operand = ZAslice[n, esize, vertical, slice]; bits(VL) result = Z[d]; for e = 0 to dim-1 bits(esize) element = Elem[operand, e, esize]; if ElemP[mask, e, esize] == '1' then Elem[result, e, esize] = element; Z[d] = result;

Operational information

If FEAT_SVE2 is enabled or FEAT_SME is enabled, then when 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.
