CS401 - Computer Architecture and Assembly Language Programming

Q. In the last 60 years, computer processors have been evolving and processing speed has increased multiple times. Increasing processor speed along with increasing the number of processing cores has been the major trend. As a computer architect, we have an option of either increasing the number of cores to achieve better performance or increasing the processing speed of a single processor. What would be your choice to go with in the prevailing scenario keeping in view the pros and cons of each approach? Provide logical reasoning in either case.

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 Note: You can consult to alphabet’s ASCII values through this link:

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”
