Question

If the pipeline is flushed for every 15 instructions, then find the number of clock cycles required to execute 1501 instructions with the pipeline method?

(a) 100
(b) 101
(c) 102
(d) 103

Answer 1

To execute 1501 instructions with the pipeline method, it would require 101 clock cycles.

Step-by-step explanation:

To find the number of clock cycles required to execute 1501 instructions with the pipeline method, we need to divide the total number of instructions by the number of instructions flushed per cycle. In this case, the pipeline is flushed for every 15 instructions. So, the number of clock cycles required would be:

1. Number of instructions / Number of instructions flushed per cycle
2. 1501 / 15 = 100.0666667

Since we cannot have a fraction of a clock cycle, we need to round up to the nearest whole number. Therefore, the number of clock cycles required would be 101.
