answer both questions and answer all details correctly .
answer only if you know the correct answer. I will thumbs up. If answer is wrong then I will thumbs down
CPS310 – COMPUTER ORGANIZATION II
Lab #4
ARC Subroutines
Submission instruction:
Labs will be done individually. Please complete and submit this lab on D2L by the submission
deadline according to the details provided by your TA. Each student should submit a pdf file that
includes all their written work and screenshots of the results of the simulations. Please note that
Lab 4 will be graded based on correct completion of the following questions in addition to the
answer to TA’s questions.
Notes:
• Make sure you store and restore the registers used by the subroutine.
• Pass all the parameters via stack data structure between caller and callee unless specified
otherwise.
PART A – myFact
Write a program that calls a subroutine called myFact by passing a positive integer value via
stack. The subroutine myFact calculates factorial of the positive integer value and returns the
result in register %r3. Then the caller program stores the result in the memory location 4048.
PART B – SQRT
Write a program that calls a function called SQRT by passing a positive integer value via stack.
SQRT performs a square root of the positive integer number and returns the result in register
%r3. Then caller program stores the result in the memory location 6048.
Note: SQRT calculates the closest integer value the square root of the positive number. A few examples
are provided below.
sqrt(13) returns 4
sqrt(12) returns 3
sqrt(10) returns 3
sqrt(9) returns 3
sqrt(8) returns 3
sqrt(5) returns 2
sqrt(4) returns 2
sqrt(3) returns 2
