Interesting, so you mean having a strided index vector [0, 1, ..., vector_size, vector_size + 1, ..., i_width, 0 + stride, 1 + stride, ...]? What about something like i_width = 12 and a 64-bit strided element (that doesn't cover all of i_width but would require another 32-bit strided element)? Wouldn't we still need a mechanism to "fill" up to i_width?
