Q1. Explain the floating point representation. Symbolize the number (+46.5)10 as a floating-point binary number with 24 bits. The normalized fraction mantissa consists of 16 bits and the exponent consists of 8 bits.
Q2. Describe the importance of RTL in the implementation of the digital systems.
Q3. Compare the terms hardwired and micro programmed control design. Give their respective merits and demerits. Write down the formats of horizontal and vertical micro-instructions.
Q4. A computer consists of 16 registers, an ALU (arithmetic logic unit) with 32 operations and a shifter with eight operations, all connected to a common bus system.
a) Formulate a control word for a micro-operation.
b) Specify the number of bits in each and every field of the control word and give a general coding scheme.
c) Show the control word which specifies the micro-operation R4 ← R5 + R6.
