Draw the internal block diagram of 8086 microprocessor and explain the functions of bus interface unit.

a) A microprocessor's circuitry consists of buses, which are electrically conductive pathways. As a result, current may flow freely between the different components. As an expert in microprocessors, identify and describe these buses and their purposes. b) What is the difference between data and instructions in a microprocessor?

Describe the set architecture's protection and instruction mechanisms.

What is instruction latency, and how is it affected by pipelining?

write a STRUCTURAL verilog code to find 1's complement & 2's complement for a variable ( compile verilog online is prefered to use !)

Write one advantage each of memory-mapped I/O and instruction based I/O.

a) The circuitry of a microprocessor comprises conductive routes referred to as buses. As a consequence, current is permitted to flow between the various components. As a microprocessor specialist, classify and characterise these buses and their functions. b) In a microprocessor, what is the difference between data and instructions?

Describe how microprogramming can be used to implement complex ALU instructions efficiently.
