Technology innovation and technology leadership are not possible for technology companies without a never-ending attention to risk and its management. Using Moore's Law as a roadmap, we, at Intel, need to translate the roadmap into innovative products for the market place and to manage the risk associated with product innovations. This includes both processor microarchitecture innovation and silicon process innovations; both of which go hand in hand. We have developed a model to minimize the risk associated with the introduction of new silicon processes and microarchitectures by alternating our focus. This cadence between microarchitecture and the silicon cycle is referred to as the "tick-tock" model [1]. The term "tick-tock" comes from the steady recurrent ticking sound made by a clock. Each "tick" represents the silicon process beat rate, which has a corresponding "tock" representing the design of a new microarchitecture delivered in a cycle approximately every two years. This model minimizes the risk associated with the introduction of new silicon processes and microarchitectures by alternating the focus from silicon to microarchitecture.
