In-situ timing monitoring methods for variation-resilient designs

2014 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2014
With technology scaling, process, voltage, and temperature (PVT) variations pose great challenges on integrated circuit designs. Conventionally, LSI circuits are designed by adding pessimistic timing margin to guarantee "always correct" operations even under worst-case conditions.

Accurate Real-Time Disparity Estimation with Variational Methods

2009
Estimating the disparity field between two stereo images is a common task in computer vision, e.g., to determine a dense depth map. Variational methods currently are among the most accurate techniques for dense disparity map reconstruction. In this paper a multi-level adaptive technique is combined with a multigrid approach that allows the variational ...

Time-Dependent Perturbation-Variation Method. II

The Journal of Chemical Physics, 1964
It is shown that the time-dependent perturbation-variation method recently developed by the author and that previously developed by Karplus and Kolker are equivalent.

Time-Dependent Perturbation—Variation Method

The Journal of Chemical Physics, 1963
Through the use of the time-ordered perturbation expansion, an operator equation for the time-dependent perturbation problem, of the same form as occurs in the time-independent problem, is generated. Thus, a variational method can be used to study the time-dependent case as well as the time-independent case.

Real-Time Optic Flow Computation with Variational Methods

2003
Variational methods for optic flow computation have the reputation of producing good results at the expense of being too slow for real-time applications. We show that real-time variational computation of optic flow fields is possible when appropriate methods are combined with modern numerical techniques. We consider the CLG method, a recent variational
