Where i is the bit index on the byte (0 being the least significant bit and 7 being the most significant bit). A and B are the registers used as inputs. P(last)i is the latest iteration of Pi. For example, P(last)1 is P1,1, since steps 3 and 4 don't apply to i=1. Similarly, G(last)i is the latest iteration of Gi. | Where i is the bit index on the byte (0 being the least significant bit and 7 being the most significant bit).
