Q1. Draw the block diagram to implement subsequent register transfer statement
yT2 : R2?R1, R1?R2


Q2. A digital computer has a common bus system for 16 registers of 32 bit every. The t2bus is constructed with multiplexers.
(a) How many selection inputs are there in every multiplexer?
(b) What sizes of multiplexers are needed?
(c) How many multiplexers are there in the bus?


Q3. The adder- subtractor circuit has the subsequent values for input mode M and data inputs A & B. In every case determine the values of the outputs: S3, S2, S1, S0 and C4
M A B
0 0111 0110
0 1000 1001
1 1100 1000
1 0101 1010
1 0000 0001









Q4. Design a 4 bit combinational circuit incrementer and decrementer using full adders.


Q5. Register A holds the eight bit binary 11011001. Determine the B operand and the logic micro operation to be performed in order to change the value in A to (a) 01101101 (b) 11111101


Q6. Starting from initial value of R=11011101, determine the sequence of binary values in R after a logic shift left followed by circular shift right, followed by a logical shift right and a circular shift.


Q7. How are data, address and control buses involved in data transfer to and from memory? Consider a computer system with 16 registers of 32 bit every and RAM of 1GB. compute the size of data bus and address bus needed for the identical.
