Microarchitecture, also known as computer organization, is a detailed design level of a computer's processor architecture, fundamental to the performance and efficiency of the computer. Coursera's Microarchitecture catalogue teaches you about the design principles and techniques used in modern computer processors. You'll learn about the role of microarchitecture in executing a computer's instruction set, including aspects like instruction pipeline, cache memory, and data path design. By grasping the intricacies of performance evaluation, power consumption, and optimization, you'll gain the ability to critically analyze and design efficient computer systems be it as a hardware engineer, computer scientist, or someone looking to transition into these fields.
