    <brief>Multi-vector unsigned integer multiply-add long long by indexed element</brief>
    <description>
      <para>The instruction operates on one, two, or four ZA quad-vector groups.</para>
      <para>This unsigned integer multiply-add long long instruction multiplies each unsigned 8-bit or 16-bit element in the one, two, or four first source vectors with each unsigned 8-bit or 16-bit indexed element of second source vector, widens each product to 32-bits or 64-bits and destructively adds these values to the corresponding 32-bit or 64-bit elements of the one, two, or four ZA quad-vector groups.</para>
      <para>The elements within the second source vector are specified using an immediate element index which selects the same element position within each 128-bit vector segment. The index range is from 0 to one less than the number of elements per 128-bit segment, encoded in 3 to 4 bits depending on the size of the element. The lowest of the four consecutive vector numbers forming the quad-vector group within all, each half, or each quarter of the ZA array are selected by the sum of the vector select register and immediate offset, modulo all, half, or quarter the number of ZA array vectors.</para>
      <para>The <arm-defined-word>vector group</arm-defined-word> symbol, <syntax>VGx2</syntax> or <syntax>VGx4</syntax>, indicates that the ZA operand consists of two or four ZA quad-vector groups respectively. The <arm-defined-word>vector group</arm-defined-word> symbol is preferred for disassembly, but optional in assembler source code.</para>
      <para>This instruction is unpredicated.</para>
      <para>ID_AA64SMFR0_EL1.I16I64 indicates whether the 16-bit integer variant is implemented.</para>
