a program x running on processor a has a global cpi of 2 and a clock frequency of 2 ghz. the same program x running on processor b has a global cpi of 5 and a clock frequency of 5 ghz. which processor is more likely to have a deeper pipeline (i.e., more number of pipeline stages)? you may assume an in-order processor design for both a and b. if you want, you may assume the same instruction count value for both a and b as well.
