Q1. Write a subroutine that will take two arrays Array1 & Array2. Array1 will contain uppercase alphabets from A-M and the Array2 will contain lower case alphabets from n-z. Your subroutine should work in such a way that it will convert array1 elements to lower case and array2 elements to uppercase and populate them in a 3rd array. (Marks 20)
For example:
Array1 = A,B,C,D,E,F,G,H,I,J,K,L,M
Array2= n,o,p,q,r,s,t,u,v,w,x,y,z
Output should be:
Array3= a,b,c,d,e,f,g,h,I,j,k,l,m,N,O,P,Q,R,S,T,U,V,W,X,Y,Z

[email protected]vu.edu.pkQ1. Write a subroutine that will find the first even number from an array of your VU ID and calculate its factorial. (10 Marks)
Note: Skip 0’s in your VU ID as shown below,
VU ID: BC190206435
After skipping 0’s, array would be:
Array: 1, 9, 2, 6, 4, 3, 5
The first even number is 2 in the array so its factorial will be calculated and saved in AX register.Q2. Write a code in assembly language (using appropriate jumps) equivalent to this given code in C. (10 Marks)
#include <stdio.h> int main() { int n1=1, n2=2; int largest; if( n1>n2) largest=n1; else largest = n2; return 0; }“The End”

Basic DOSBox and NASM understanding to run assembly code
Various Addressing modes to access memory
NOTE
No assignment will be accepted after the due date via email in any case (whether it is the case of load shedding or internet malfunctioning etc.). Hence refrain from uploading assignment in the last hour of deadline. It is recommended to upload solution file at least two days before its closing date.
If you people find any mistake or confusion in assignment (Question statement), please consult with your instructor before the deadline. After the deadline no queries will be entertained in this regard.
For any query, feel free to email atProblem Statement:
Code written in Word Screenshot of compilation step (DOSBox) Screenshot of AFD
Save your complete VUID in memory using Base Register Indirect + Offset addressing mode (if last digit of your VUID is Odd) or Indexed Register Indirect + Offset addressing mode (if last digit of your VUID is even).
Detailed Instructions:
This assignment will give hands on experience of how to run assembly language code using DOSBox and NASM. First, you have to define labels for storing your VUID and then store each alphabet/digit of VUID, step by step, in to any general purpose registers. Finally, store the alphabet/digit from general purpose register to respective memory location (which you have defined by label in above step).
Addressing Modes to use:
In order to access VUID and storing it in memory, you have to use ONE of the following addressing modes:
Base Register Indirect + Offset (only if last digit of your VUID is Odd)
Indexed Register Indirect + Offset (only if last digit of your VUID is Even)
NOTE: Zero marks will be awarded, if you do not follow proper addressing mode.
What to Submit:
After writing your code, open DOSBox and run NASM (as described in video tutorial shared in Announcement page of this course). Assemble the code using nasm command and take screenshot. After that, open the COM file in debugger (AFD).
Run your code by pressing F1 key until last statement of code is reached. At this stage, Data Window # 2 of AFD should display your complete VUID (at consecutive locations; see below example). Also take screenshot of AFD.
Your assignment must be submitted as a SINGLE WORD document (DOC or DOCX) with:
NOTE: When you take screenshot of compilation step and AFD, take screenshot of whole screen, not of DOSBox and AFD. Cropping or any tempering with screenshot will result in ZERO marks.Example:
Suppose a student VUID is BC123456789. The last digit of this VUID is 9 which is an Odd number. So, this student will use Base Register Indirect + Offset addressing mode to solve this assignment.
Sample screenshot of final output:
Note that Data Window # 2 is showing student VUID:463f2031-23ba-4a9a-9aa8-96ca3153d5ee-image.png
Helping Material:
Detailed video tutorial of how to use DOSBox and NASM is already shared with you in Announcement page of this course
Command to manipulate Data Windows of AFD is mentioned in AFD tutorial (link is given in the same Announcement)
Use ASCII table for first two alphabets of your VUID

Question Title Cortex-A OR Cortex-M
Question Description
A smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others. It has a touch screen interface providing features like GPS tracking, heart rate and sleep monitoring etc. with power efficient batteries. The ARM Cortex processors are used in smartwatches providing several benefits.Suppose we have to choose between ARM Cortex-A or Cortex-M series architecture for our next generation smartwatch. Which one would you select between the two and why? Support your selection of either architecture with solid reasoning considering memory management, cost, performance and chip size.
Important Instructions:
- Please note that no extra time will be given for posting comments on GDB.
- Use the font style “Times New Roman” with font size “12”.
- Do not copy or exchange your answer with other students. Two identical comments will be marked zero.
- Your comments should not exceed 120 words.
