What are the differences between RISC and CISC architectures?

What are the differences between RISC and CISC architectures?

RISC (Reduced Instruction Set Computer) focuses on a small set of simple instructions, while CISC (Complex Instruction Set Computer) has a larger set of more complex instructions. RISC aims for efficiency and speed, whereas CISC aims for more functionality per instruction.

Can you give examples of each architecture?

Sure! An example of a RISC architecture is ARM, commonly used in mobile devices. An example of a CISC architecture is x86, used in most personal computers.

Which one is better for performance?

It depends on the application. RISC can offer better performance for tasks requiring high speed and efficiency, while CISC can be more efficient for complex tasks due to its rich instruction set.

Are there any modern processors that use RISC or CISC?

Yes, modern processors like Apple's M1 chip use RISC architecture, while Intel and AMD processors typically use CISC architecture.
