I think part of the challenge is to not exceed the word size, 16 bits in this case.

- kragen 2y agothat's useful with explicit simd instructions which let you process 32 (pairs of corresponding) 16-bit pixels with one avx-512 instruction, or on a 16-bit machine like the 80286, but unnecessary if you're processing a single pair of 16-bit pixels with 32-bit instructions. on the other hand, you might have 32-bit vectors or something, for example for the standard axis-aligned bounding box test
