Assume that we have an application with a total of 500,000 instructions where 20% of them are the load/store instructions with a
balu736 [363]

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

riadik2000 [5.3K]

Answer:

In Python:

cents = int(input("Cents: "))

dollars = int(cents/100)

quarters = int((cents - 100*dollars)/25)

dimes = int((cents - 100*dollars- 25*quarters)/10)

nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)

pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels

if not(dollars == 0):

   if dollars > 1:

       print(str(dollars)+" dollars")

   else:

       print(str(dollars)+" dollar")

if not(quarters == 0):

   if quarters > 1:

       print(str(quarters)+" quarters")

   else:

       print(str(quarters)+" quarter")

if not(dimes == 0):

   if dimes > 1:

       print(str(dimes)+" dimes")

   else:

       print(str(dimes)+" dime")

if not(nickels == 0):

   if nickels > 1:

       print(str(nickels)+" nickels")

   else:

       print(str(nickels)+" nickel")

if not(pennies == 0):

   if pennies > 1:

       print(str(pennies)+" pennies")

   else:

       print(str(pennies)+" penny")

   

Explanation:

A prompt to input amount in cents

cents = int(input("Cents: "))

Convert cents to dollars

dollars = int(cents/100)

Convert the remaining cents to quarters

quarters = int((cents - 100*dollars)/25)

Convert the remaining cents to dimes

dimes = int((cents - 100*dollars- 25*quarters)/10)

Convert the remaining cents to nickels

nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)

Convert the remaining cents to pennies

pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels

This checks if dollars is not 0

<em>if not(dollars == 0):</em>

If greater than 1, it prints dollars (plural)

<em>    if dollars > 1:</em>

<em>        print(str(dollars)+" dollars")</em>

Otherwise, prints dollar (singular)

<em>    else:</em>

<em>        print(str(dollars)+" dollar")</em>

This checks if quarters is not 0

<em>if not(quarters == 0):</em>

If greater than 1, it prints quarters (plural)

<em>    if quarters > 1:</em>

<em>        print(str(quarters)+" quarters")</em>

Otherwise, prints quarter (singular)

<em>    else:</em>

<em>        print(str(quarters)+" quarter")</em>

This checks if dimes is not 0

<em>if not(dimes == 0):</em>

If greater than 1, it prints dimes (plural)

<em>    if dimes > 1:</em>

<em>        print(str(dimes)+" dimes")</em>

Otherwise, prints dime (singular)

<em>    else:</em>

<em>        print(str(dimes)+" dime")</em>

This checks if nickels is not 0

<em>if not(nickels == 0):</em>

If greater than 1, it prints nickels (plural)

<em>    if nickels > 1:</em>

<em>        print(str(nickels)+" nickels")</em>

Otherwise, prints nickel (singular)

<em>    else:</em>

<em>        print(str(nickels)+" nickel")</em>

This checks if pennies is not 0

<em>if not(pennies == 0):</em>

If greater than 1, it prints pennies (plural)

<em>    if pennies > 1:</em>

<em>        print(str(pennies)+" pennies")</em>

Otherwise, prints penny (singular)

<em>    else:</em>

<em>        print(str(pennies)+" penny")</em>
