What are the ways of passing parameters and returning results in a subroutine in assembly ?
`Hey,
Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
Passing the parameter through the registers is easy and the subroutine assume that parameters are already placed in the registers. Results of a subroutine can also returned in the registers or the memory location to store the results can be passed as parameters via the registers.
Kindly revert for any queries
Thanks.

Consider a subroutine swap that takes two parameters and simply swaps their values. For example, after calling swap(X,Y), X should have the original value of Y and Y the original value of X. Assume that variables to be swapped can be simple or subscripted (elements of an array), and they have the same type (integer). Show that it is impossible to write such a general-purpose swap subroutine in a language with: Parameter passing by name. Hint: for the case of...
i am trying to write a subroutine in assembly that removes all occurrences of a given character in a string. The subroutine takes two parameters: the string pointer, and the character to be removed. Write a C code that calls this subroutine. The string is defined in the C source code file as global. Assume the assembly and C code are in separate files. Use Keil/uVision to test your program where the C code should ask the assembly subroutine to...
must be written in assembly code Write an MSP430 assembly language subroutine, REP_FREE, to examine the elements of an array of positive word-size numbers stored at location ARRAY_IN. The array is already sorted in an ascending order. The first element is the number, n,which is the length of the array. The subroutine will copy the elements from location ARRAY_IN to location ARRAY_OUT. While copying, if an element appears more than once (repeated), then the repeated copies are ignored. In essence,...
please show work and explain steps
Implement the following subroutine in PIC24 assembly language. Use the policy estab- lished in this chapter for using working registers for subroutine parameters and loca II this subroutine implements an uint16 t swap. void u16-swap(uint16-t* pul 6-х, uint8-t u8-1, uint8-t u8.j)( ls uint16-t u16_k; u16-k = pu16-XLu8-1);

How would you go about creating a subroutine in MARIE assembly language that allows for the output of text entered from a keyboard?
Problem 2: Write a friendly assembly language subroutine, called Ports_Init, to configure the pins on Port F as follows: pins 0,4 are inputs and 2,3 are outputs. (10 Points)
5. (15 points) Write an ARM assembly subroutine that finds the absolute value of an integer input. Follow register conventions. // |x| → The absolute value of a number is its distance from zero. // C-based function prototype: int abs(int x)
Write an ARM assembly language subroutine (named nfibo) to calculate and return the n-th Fibonacci number. Fibonacci numbers (or a Fibonacci sequence) are a series of numbers with a property that the next number in the series is a sum of previous two numbers. Starting the series from 0, 1 as the first two numbers we have 0, 1, (0 + 1) = 1, (1 + 1) = 2, (1 + 2) = 3, (2 + 3) = 5, (3...
