Actually, that would be a problem. That would be the only instruction writing a register pair, so you'd be paying the extra hardware cost just for that one instruction. But it could be pushed out to the HI and LO registers without any extra cost. -Pete _______________________________________________ OpenRISC mailing list [email protected] http://lists.openrisc.net/listinfo/openrisc
