This paper addresses a system for fast object tracking based on texture cues, by using the wavelet transform and a fuzzy grammar classifier. The method is based on wavelet type features. The feature vector consists of 6 characteristics extracted from the wavelet detail images for each colour component. These texture characteristics automatically generate a(More)
As the interconnections dominate the circuit delay in nanometer technologies, placement plays a major role to achieve timing closure since it is a main step that defines the interconnection lengths. In initial stages of the physical design flow, the placement goal is to reduce the total wirelength, however total wirelength minimization only roughly(More)
——Energy-efficient fast adders are needed in the design of battery-powered portable devices. Although many fast adder architectures exist, most of them require transistor-level optimizations that prevent their synthesis in a standard-cell flow. This paper presents two energy-efficient Add-One Carry-Select Adders (A1CSA and A1CSAH) suited for standard-cells(More)
Meeting timing requirements and improving routability are becoming more challenging in modern design technologies. Most timing-driven placement approaches ignore routability concerns which may lead to a gap in routing quality between the actual routing and what is expected. In this paper, we propose a routing-aware incremental timing-driven(More)
Due to the advanced stage of development on EDA science, it has been increasingly difficult to implement realistic software infrastructures in academia so that new problems and solutions are tested in a meaningful and consistent way. In this paper we present Rsyn, a free and open-source C++ framework for physical synthesis research and development(More)
