Consider two registers A and B and we transfer data from A to B in a serial in/ serial out shift fashion, suppose the contents in A and B are 01101101, and 10100010 respectivley, what are the contents in A and B after four consecutive clock cycles?

Solution

contents of A and B are given initially:

A B   

01101101 10100010

After first clock cycle:

00110110 11010001

After second clock cycle:

00011011 01101000

After third clock cycle:

00001101 10110100

After fourth clock cycle:

00000110 11011010
