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?

Explain the concept of microcode in the context of ALU instruction execution. How does microcode influence the operation of the ALU?

What are the fundamental operations performed by an ALU, and how are they executed within the CPU?

Discuss the concept of pipelining in ALU instructions and its impact on CPU performance.

Explain the concept of instruction pipelining in CPU design. What are the key stages in an instruction pipeline, and how do they function?

Explain the concept of pipelining in computer architecture. How does it improve processing efficiency?

Programs written for zero-address, one-address, or two-address architecture are more likely to be longer (have more instructions). Why?

Explain the concept of pipelining in ALU instructions. How does it improve instruction execution throughput?
