In an assignment given on CSE211, a student is assigned the following task

3. Consider PC = last digits of your registration no(i.e 69)

4. Place your date of birth including your date and month of birth(i.e 20 oct 2000) into the DR

eg: 0108 – 01 date and 08 as month

5. Now perform the below given task

AR  PC

M[AR] DR

IR M[AR]

Explain the contents of the memory after the execution of second instruction.

IF PC= 682 , AR=123 , DR=A2BF, IR= 5672, then execute the following M[AR] DR IR M[AR] Determine the value of IR after the execution and comment on the type of addressing.

The 8-bit registers AR, BR, CR, and DR initially have the following values: AR= 11010010, BR= 11100011, CR= 10111001 , DR= 10101011 Determine the 8-bit values in each register after the execution of the following sequence of microoperations. AR <-AR + BR CR <- CR ^ DR, BR <- CR + 1 AR <-AR – CR 

In an assignment given on CSE211, a student is assigned the following task 1. Consider AR= last digits of your registration no 2. Place your date of birth including your date and month of birth into the TR eg: 0108 – 01 date and 08 as month M[AR]  TR IR M[AR] 

Design an arithmetic circuit with one selection variable S and two n-bit data inputs A and B. The circuit generates the following four arithmetic operations in conjunction with the input carry Cin. Draw the logic diagram for the first two stages. 5 marks S Cin =0 Cin= 1 0 D = A + B (add) D = A + 1 (increment) 1 D = A - 1 (decrement) D = A + B’ + 1 (subtract)  

Starting from an initial value of R in Hex is AF determine the sequence of binary values in R after a logical shift-left, followed by a circular shift-right, followed by a logical shift-right and a circular shift-left. explain through the proper diagrams. 

 Show the hardware that implements the following statement. Include the logic gates for the control function and a block diagram for the binary counter with a count enable input. xyT0 + T1 + y’ T2: AR  AR + 1
