I have a question about execution timing of MC68010. According to the manual, MC68010 executes an instruction exactly in its defined execution time.(except for "conditional branch") For example, "addw d0,d1" always takes 4 clock cycles. (Here, I assume that the instruction is already prefetched and there is no exception like interrupt or bus error.) Is this always correct? If not, what kind of factors make the execution time nondeterministic? Thank you. ------- ChangYun Park cypark@june.cs.washington.edu
