CPU Architecture

What is the primary function of the CPU in a computer system?

• The primary function of the CPU in a computer system is to store data

• The primary function of the CPU in a computer system is to carry out instructions from computer programs by performing basic arithmetic, logic, control, and input/output operations specified by the instructions.

• The primary function of the CPU in a computer system is to play music and videos

• The primary function of the CPU in a computer system is to cool down the computer

Explain the difference between Harvard architecture and von Neumann architecture.

• Harvard architecture uses only one memory space for data and instructions, while von Neumann architecture uses separate memory spaces.

• Harvard architecture uses a single memory space for both data and instructions, while von Neumann architecture has separate memory spaces.

• Harvard architecture and von Neumann architecture both use separate memory spaces for data and instructions.

• Harvard architecture has separate memory spaces for data and instructions, while von Neumann architecture uses a single memory space for both data and instructions.

What are the main components of a CPU?

• Operating system, software, applications, and files

• The main components of a CPU are the control unit, arithmetic logic unit, registers, and cache.

• RAM, hard drive, motherboard, and power supply

• Keyboard, mouse, monitor, and printer

Describe the fetch-decode-execute cycle in CPU operation.

• The fetch-decode-execute cycle is the process by which the CPU retrieves instructions from the hard drive, decodes them, and then executes the instructions to perform the desired operation.

• The fetch-execute-retrieve cycle is the process by which the CPU stores instructions in memory, decodes them, and then executes the instructions to perform the desired operation.

• The fetch-decode-execute cycle is the process by which the CPU retrieves instructions from memory, decodes them, and then executes the instructions to perform the desired operation.

• The fetch-decode-execute cycle is the process by which the CPU retrieves data from memory, decodes it, and then executes the data to perform the desired operation.

What is the role of the control unit in a CPU?

• The control unit in a CPU is responsible for printing documents

• The control unit in a CPU is responsible for coordinating the activities of the other units within the CPU, interpreting instructions, and directing the flow of data within the CPU.

• The control unit in a CPU is responsible for cooking meals

• The control unit in a CPU is responsible for making phone calls

Explain the concept of pipelining in CPU architecture.

• Pipelining in CPU architecture is a technique where instructions are executed one at a time, slowing down the overall performance.

• Pipelining in CPU architecture refers to the physical pipes used to cool down the CPU during operation.

• Pipelining in CPU architecture is a process where the CPU is divided into multiple smaller units, reducing its efficiency.

• Pipelining in CPU architecture is a technique where multiple instructions are overlapped in execution, allowing the CPU to work on several instructions at once. This improves overall throughput and performance.

What is the purpose of the arithmetic logic unit (ALU) in a CPU?

• The purpose of the ALU in a CPU is to store data temporarily

• The purpose of the ALU in a CPU is to control the input/output operations

• The purpose of the ALU in a CPU is to manage the flow of electricity within the CPU

• The purpose of the ALU in a CPU is to perform arithmetic and logical operations on the data that is being processed.

Discuss the role of the cache memory in CPU performance.

• Cache memory in CPU helps to improve performance by storing frequently accessed data and instructions, reducing the need to access the slower main memory.

• Cache memory in CPU slows down performance by taking up space

• Cache memory in CPU only stores data that is rarely accessed

• Cache memory in CPU has no impact on performance

What is the difference between RISC and CISC CPU architectures?

• RISC and CISC architectures are both based on the same set of instructions.

• The main difference is that RISC (Reduced Instruction Set Computing) has a smaller set of simple instructions, while CISC (Complex Instruction Set Computing) has a larger set of complex instructions.

• RISC and CISC architectures have no difference.

• The difference is that RISC has a larger set of complex instructions, while CISC has a smaller set of simple instructions.

Explain the concept of parallel processing in CPU design.

• Parallel processing in CPU design is the process of combining multiple CPUs into a single unit, which does not improve performance or efficiency.

• Parallel processing in CPU design means that a CPU can only handle one task at a time, causing inefficiency in handling complex tasks.

• Parallel processing in CPU design refers to the ability of a CPU to execute tasks one after the other, leading to slower performance.

• Parallel processing in CPU design refers to the ability of a CPU to execute multiple tasks or processes simultaneously, by dividing the workload among multiple cores or threads. This allows for improved performance and efficiency in handling complex tasks.
