Answer:
Part 1.7 :The number of instructions in a second are 500 Million instructions
Part 1.8 :The number of instructions in a minute are 30 Billion instructions
Part 1.9 : The number of years required are as 57 years.
Explanation:
Part 1.7
500MHz means there are 500 million clock cycles per second
so the execution rate is 500 Million instructions per second
The number of instructions in a second are 500 Million instructions
Part 1.8
As 1 minute = 60 seconds
so 60 * 500 Million per second = 30 Billion instructions!
The number of instructions in a minute are 30 Billion instructions
Part 1.9
The execution rate is given as 1000 instructions per second thus
30 Billion instructions / 1000 = 30 million minutes
There are 60 minutes per hr
so 30 million minutes is 500,000 hrs
As there are 24 hrs per day
so 500,000 /24 = 20833 days = about 57 years
The number of years required are as 57 years.
