A common bus system which is capable of transferring 2 bits at time with number of registers are 4 each register is of 2 bit? Draw circuit diagram for this and also define how many multiplexers are required and what will be the size of multiplexer with truth table Also explain how to gather data from this bus back into registe

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 

. 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

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.

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 B2 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 ç AR

The 8-bit registers R1, R2, R3, and R4 initially have the following values:

R1 - 1111 0010, R2- 11111111 , R3- 1011 1001 , R4-11101010 . Determine the 8-bit values in each register after the execution of the following sequence of microoperations. 1) R1 <-R1 + R2 , 2) R3<- R3 ^ R4, R2 <-  R2 + 1 , 3) R1 <- R1 – R3
