This is an arithmetic shift right (ashr) operation which AC and QR ti the right and leaves the sign bit in AC unchanged. Reply Delete. Typically, it proceeds from LSB to MSB, starting at i = 0; the multiplication by 2i is then typically replaced by incremental shifting of the P accumulator to the right between steps; low bits can be shifted out, and subsequent additions and subtractions can then be done just on the highest N bits of P.[2] There are many variations and optimizations on these details.
