> ... and adding an integer to a pointer would be hellaciously expensive. Fair, though if it were only the PC and instruction memory that were permuted that isn't much of an issue. It's not that bad the circuit looks more like a multiplier rather than an adder. (search term would be LFSR fast-forward or jump-ahead). PC is updated presumably on every cycle, while adding an an integer to it is probably a rare operation (just don't use computed jumps...).
