Consider two different implementations of the same instruction set architecture. the instructions can be divided into four classes according to their cpi . we’ll label them a: integer, b: floating point, c: load/store and d: control. assume our program runs for 2 million instructions.
more data you'll need:
p1 clock rate 7.12 ghz
p2 clock rate 6.98 ghz
p1 cpi p2 cpi ic %
class a 2.13 3.59 13
class b 3.16 3.38 35
class c 1.87 3.75 27
class d 1.21 1.98 25
to walk through an example, the integer instructions, which we labeled a, requires 2.13 cycles per instruction on p1, 3.59 on p2, and represent 13 % of all of the 2 million total dynamic instructions given to each processor.
(a) how many instructions are run in each category by each processor?
class a :
class b :
class c :
class d :
total : 2.00e+06
