Arm Education in Conversation with Sophie Wilson

Video Description

Welcome to the ‘Arm Education In Conversation With…’ series of interviews. In this episode, we interview Sophie Wilson, a renowned computer scientist and engineer who co-designed the first Arm processor. Sophie shares with us her insights into the genesis of the project, the fundamentals of computer architecture design, and why making things is still important in today’s world.
