1 Brunvand, Erik L.A comparison of modular self-timed design stylesState-machine sequencing methods in modular 2-phase and 4-phase asynchronous handshake control are compared. Design styles are discussed, and the sequencers are tested against each other using a medium-scale minicomputer test design implemented in FPGAs. Seven 4-phase sequencers are tested. In these...Self-timed; State-machine sequencing; Asynchronous handshake control1995
2 Smith, Kent F.A fast parallel squarer based on divide-and-conquerFast and small squarers are needed in many applications such as image compression. A new family of high performance parallel squarers based on the divide-and-conquer method is reported. Our main result was realizing the basis cases of the divide-and-conquer recursion by using optimized n-bit primiti...Squarer; Parallel squarers; Divide-and-conquer; MOPS; CMOS1995
3 Mathews, V. JohnA new model of perceptual threshold functions for application in image compression systemsThis paper discusses the development of a perceptual threshold model for the human visual system. The perceptual threshold functions describe the levels of distortions present at each location in an image that human observers can not detect. Models of perceptual threshold functions are useful in ima...1995

8 Mathews, V. JohnAn optimal design procedure for intraband vector quantized subband codingAbstTact- Subband coding with vector quantization is addressed in this paper. Forming the data vectors from both between and within the subbands is considered. The former of these two schemes is referred to as interband coding and the latter as intraband coding. Interband coder design is relatively ...1995

11 Brunvand, Erik L.Automatic rapid prototyping of semi-custom VLSI circuits using actel FPGAsAbstract : We describe a technique for translating semi-custom VLSI circuits automatically into field programmable gate arrays (FPGAs) for rapid prototyping to develop a system. Using an array multiplier as an example of this translation, the VLSI circuits are designed using a cell-matrix based envi...1995

22 Henderson, Thomas C.Evolutionary teleomorphologyThe physical layout of organs and neural structures in biological systems is important to their functioning, and is the result of evolutionary selection forces. We believe this is true even at the individual neuron level, and should be accounted for in any bio-based approach. In particular, when tr...Evolutionary teleomorphology; Bio-based approach; Physical layout problem; PLP; Neurons; Nodes1995
23 Gopalakrishnan, GaneshExplicit-enumeration based verification made memory-efficientWe investigate techniques for reducing the memory requirements of a model checking tool employing explicit enumeration.
