SDOT (2-way, indexed): Signed integer dot product by indexed element (two-way)
SDOT Zda.H, Zn.B, Zm.B[imm] (SVE2.3 (SME2.3
128-bit SVE
For each pair of signed 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
256-bit SVE
For each pair of signed 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
512-bit SVE
For each pair of signed 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
