128-bit SVE
For each 16-bit element, use a 2-bit index from a segment of (1) to look up a 16-bit element from the table in the low part of (2), writing the result to (3). The segment is selected by the immediate index.
256-bit SVE
For each 16-bit element, use a 2-bit index from a segment of (1) to look up a 16-bit element from the table in the low part of (2), writing the result to (3). The segment is selected by the immediate index.
512-bit SVE
For each 16-bit element, use a 2-bit index from a segment of (1) to look up a 16-bit element from the table in the low part of (2), writing the result to (3). The segment is selected by the immediate index.
