128-bit SVE
Decode (1) from predicate-as-counter representation to a quadruple-length predicate, select the half indicated by imm, and copy the bits corresponding to 16-bit elements to two consecutive destination registers (2), zeroing all other bits.
256-bit SVE
Decode (1) from predicate-as-counter representation to a quadruple-length predicate, select the half indicated by imm, and copy the bits corresponding to 16-bit elements to two consecutive destination registers (2), zeroing all other bits.
512-bit SVE
Decode (1) from predicate-as-counter representation to a quadruple-length predicate, select the half indicated by imm, and copy the bits corresponding to 16-bit elements to two consecutive destination registers (2), zeroing all other bits.
