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). 7 _% u2 R7 @3 @$ Q [7 E3 X7 [
