Both processors are very similar to program. PowerPC offers substantial increase in performance, lower logic consumption, DCR and PLB bus. DCR bus is very handy while I think that PLB bus can replaced by OPB to simplify designs. There is a major drawback of hard processors - any errata cannot be corrected with updates (like PPC cache errata). ; D* m* q$ Q9 s7 H; ~/ m7 P/ @2 q* {# z
