Common-Case Computation: A High-Level Technique for Power and Performance Optimization
This paper presents a design methodology, called common-case computation (CCC), and new design automation algorithms for optimizing power consumption or performance. The proposed techniques are applicable in conjunction with any high-level design methodology where a structural register-transfer level (RTL) description and its corresponding scheduled behavioral (cycle-accurate functional RTL) description are available. It is a well-known fact that in behavioral descriptions of hardware (also in software), a small set of computations (CCCs) often accounts for most of the computational complexity. However, in hardware implementations (structural RTL or lower level), CCCs and the remaining computations are typically treated alike. This paper shows that identifying and exploiting CCCs during the design process can lead to implementations that are much more efficient in terms of power consumption or performance. We propose a CCC-based high-level design methodology with the following steps:...
