What is a microprocessor architecture?

Overview

A microprocessor architecture refers to the design of a Central Processing Unit(CPU). I will be talking about Complex Instruction Set Computer (CISC) and Reduced Instruction Set Computer (RISC), two popular microprocessor architectures that are widely used in the industry.

Complex Instruction Set Computer (CISC)

CISC uses complex and powerful computer commands. It is known for its memory efficiency and have been in use for a longer time that RISC processors. This type of processes are used in the popular intel x86 cpu.

Reduced Instruction Set Computer (RISC)

RISC uses small and simpler commands. It is known for its energy efficiency, which is why it is prominent in mobile devices and laptops. The processor executes one action per second. This type of processes are used in the popular Mac silicon cpu chips.
