What is a CPU microarchitecture and what are the building blocks inside a CPU? Boyd Phelps, CVP of Client Engineering at Intel, takes us through key microarchitecture concepts like pipelines, speculation, branch prediction as well as the main building blocks in the front and back end of a CPU. Want to learn about the history of CPU architecture? Check out part one here:    • Architecture All Access: Modern CPU A...  

Boyd Phelps has worked on some of the most well-known chip designs in Intel’s history, from Nehalem to Haswell to Tiger Lake and more.

Architecture All Access is a master class technology series featuring Senior Intel Technical Leaders taking an educational approach to the historical impact and future innovations of key architectures that will continue to be at the center of ‘world-changing technology that enriches the lives of every person on earth.’ If you are interested in CPUs, FPGAs, Quantum Computing and beyond, subscribe and hit the bell to get new episode notifications.
