Q1. Design a four bit priority encoder comprising of four lines P, Q, R and S. R consists of highest priority followed by the P, S and Q. Write down an application of the priority encoder.
Q2. With the proper block diagram describe the operation of a 4 bit combinational array multiplier. Describe the data flow in that array multiplier while multiplying x = (1010)2 and y = (0011)2.
Q3. What do you mean by macro? Explain how it is employed as a tool for simplifying the program design? Explain how it is distinct from subroutine?
Q4. Describe the characteristic features of the RISC and CISC Processor. Illustrate the conditions in which the RISC and CISC processors are preferable.
Q5. With proper block diagram describe the operation of a micro program sequencer.
Q6. Describe the design methodology employed for designing hardware control unit. Illustrate the merits of hardware control unit over the micro programmed control unit.
