Question
1) True and false questions: For each of the following statements explain under what conditions they are true and under what conditions they are false.
a) If two processors implement the same instruction set architecture, the one with a higher clock speed will execute programs faster than then the one with a slower clock speed.
b) If two processors implement the same instruction set architecture with the same clock speed, the one with the larger cache will be faster.
c) A Harvard architecture is needed for a processor to read both data and instructions during the same clock cycle.
d) Some processors use a big-endian representation of multi-byte numbers and others use a little-endian representation. This choice has no effect on its performance in a system.
Explanation / Answer
a) True, If two processors implement the same instruction set architecture, the one with a higher clock speed will execute programs faster than then the one with a slower clock speed as Each instruction requires some number of clock cycles. More the clock speed, more instructions it can read in same unit of time.
b) False, If two processors implement the same instruction set architecture with the same clock speed, the one with the larger cache will be faster as
c) True, A Harvard architecture is needed for a processor to read both data and instructions during the same clock cycle as in other Architecures, The CPU can do either reading data or instructions during the same clock cycle because the instructions and data use the same bus system.
d) False, Some processors use a big-endian representation of multi-byte numbers and others use a little-endian representation. This choice has effect on its performance in a system. becuase in little-endian system the address of a given value in memory taken as 32, 16 or 8 bit width is same, so we just need to change the fetch instruction not the fetching address but in big-endian System we need to increment the pointer and then perform the narrower fetch operation on the new value.
