Assume that we have an application with a total of 500,000 instructions where 20% of them are the load/store instructions with a

n average CPI of 6 cycles, and the rest instructions are ALU instructions with average CPI of 1 cycle. If we double the clock rate without optimizing the memory latency, the average CPI for load/store instruction will also be doubled to 12 cycles. What is the speedup after this change?

Answer:

1.25

Explanation:

#instructions = 5*10^{5}  

Average CPI (old) = 0.2*6 + 0.8*1 = 1.2+0.8 = 2.0

Average CPI (new) = 0.2*12 + 0.8*1 = 2.4 + 0.8 = 3.2

Assuming Clock Rate = x

Speedup = Execution Time (old) / Execution time (new)  = (2.0*5*10^{5} /x) / (3.2*5*10^{5} /2x)  = 4/3.2 = 1.25

<h2>Answer:</h2>

<u>The correct option is</u><u> (B) hang up and call back using the banks official phone number</u>

<h2>Explanation:</h2>

There are a lot of cases where people pretend to call from the banks where the receivers have the account. The caller tries to take the information from the receiver and pretends to be the bank official. If there is any doubt then the receiver should hang up the call and call back the official number of the bank to confirm that whether somebody has called from the bank to get the information.
