4-One possible performance multiplication enhancement is to do a shift and add instead of an actual multiplication. Since 9 * 6,

for example, can be written (2 * 2 * 2 + 1) * 6, we can calculate 9 *6 by shifting 6 to the left 3 times and then adding 6 to that result. Show the best way to calculate 13 * 7 using shifts and adds/subtracts. Assume both inputs are 8-bit unsigned integers.

Answer:

Check the explanation

Explanation:

The above question can be sovled in the below step by step way:

15 can be written as 16-1 = 24 -1

Therefore, 15 *13 = (24 -1)*13

= 13*24 - 13

Now, when we left shift a number we multiply it by 2k .Where k is no of times we left shifted it.

Therefore, 13*24 = shift 13 to left 4 times

15 * 13 = shift 13 to left 4 times and subtract 13 from it.

Exercise 8.1.9: Diving Contest Your school is hosting a diving contest, and they need a programmer to work on the scoreboard! Yo
vampirchik [111]

Answer:

def calculate_score(theTuple):

    first, second, third = theTuple

    if first >= 0 and first <=10 and second >= 0 and second <=10 and third >= 0 and third <=10:

         print(first + second+third)

    else:

         print("Range must be 0 to 10")

Explanation:

This line defines the function

def calculate_score(theTuple):

This line gets the content of the function

    first, second, third = theTuple

The following if condition checks if the digits are in the range 0 to 10

    if first >= 0 and first <=10 and second >= 0 and second <=10 and third >= 0 and third <=10:

This calculates the sum

         print(first + second+third)

else:

If number is outside range 0 and 10, this line is executed

         print("Range must be 0 to 10")

Suppose a program takes 1000 machine instructions to run from start to end, and can do that in 10 microseconds when no page faul
Tema [17]

Answer:

(10^6 + 9.9)

Explanation:

Given:

Total number of machine instructions = 1000

Number of page fault in 100 instructions = 1

Number of page faults in 1000 instructions = 10

Time to serve one page fault = 100 milliseconds

Time to serve ten page faults = 100*10 milliseconds = 1000 milliseconds = 10^6 Microseconds

Number of instructions without any page fault = 1000 - 10 = 990

Time required to run 1000 instructions = 10 Microseconds

So, time required to run 990 instructions = (10*(990/1000)) Microseconds = 9.9 Microseconds

So, the total time required to run the program = (10^6 + 9.9) Microseconds
