Abstract
This present invention presents a Common Case Computation (CCC) based design. A computation circuit with reduced power consumption, said computation circuit having a plurality of components. The components include a general purpose circuit, a common case detection circuit and a common case execution circuit. The common case detection circuit detects an occurrence of a common case based on a first subset of primary inputs and a first subset of internal variables for the general purpose circuit, and the common case execution circuit computes a subset of primary outputs of the general purpose circuit based on a second subset of primary inputs for the general purpose circuits and a second subset of internal variables for the general purpose circuit. The first subset of the primary inputs and the first subset of internal variables can be the same as the second subset of primary variables and the second subset of internal variables respectively. The common case computation circuit identifies and exploits common case computations during the design process for reducing power consumption.
