2. (a) Draw a block diagram for a parallel divider which is capable of dividing a positive 8-bit binary number by a positive 4-bit binary number to give a 4-bit quotient. Use a 9-bit dividend register, a 4-bit divisor register, a subtracter-comparator block and a control block. (b) Show the contents of the dividend register and the value of at each clock time when 49 is divided by 6. (C is the comparator output and should have a value of C= 1 if subtraction can take place without a negative result). (c) Under what conditions will overflow take place
