1 Riesenfeld, Richard F.; Smith, Kent F.An experimental system for computer aided geometric designThe main goal of this proposed level-of-effort project is to extend present capabilities in the area of Computer Aided Geometric Design (CAGD) and to develop custom VLSI support for some special geometric functions.Computer aided geometric design; CAGD; VLSI; Very large scale integration1984
2 Harrison, Reid R.Analog MAP decoder for (8,4) hamming code in subthreshold CMOSAn all-MOS analog tail-biting MAP decoder is presented for an (8,4) Hamming code. The decoder implements a probability propagation algorithm using subthreshold CMOS networks. Physical results verify the expected behavior of the decoder and demonstrate robustness of analog decoding circuits.MAP decoder; Hamming code; VLSI2004-01-01
3 Harrison, Reid R.Biologically inspired analog IC for visual collision detectionWe have designed and tested a single-chip analog VLSI sensor that detects imminent collisions by measuring radially expanding optic flow. The design of the chip is based on a model proposed to explain leg-extension behavior in flies during landing approaches. We evaluated a detailed version of thi...Visual collision detection; VLSI2005-11
4 Harrison, Reid R.CMOS programmable analog memory-cell array using floating-gate circuitsThe complexity of analog VLSI systems is often limited by the number of pins on a chip rather than by the die area. Currently, many analog parameters and biases are stored off-chip. Moving parameter storage on-chip could save pins and allow us to create complex programmable analog systems. In this ...Computer chips; VLSI; Computer memory; Potentiometers; CMOS circuits; Floating gate circuit2001-01
5 Gopalakrishnan, GaneshHigh level optimizations in compiling process descriptions to asynchronous circuitsAsynchronous/'Self-Timed designs are beginning to attract attention as promising means of dealing with the complexity of modern VLSI technology. In this paper, we present our views on why asynchronous systems matter. We then present details of our high level synthesis tool SHILPA that can automatic...Self-timed; VLSI1992
6 Harrison, Reid R.Local field potential measurement with low-power analog integrated circuitLocal field potentials (LFPs) in the brain are an important source of information for basic research and clinical (i.e., neuroprosthetic) applications. The energy contained in certain bands of LFPs in the 10-100 Hz range has been shown to correlate with specific arm movement parameters in nonhuman ...Local field potentials; Neural recording; Low-power circuit design; Neural prosthesis; VLSI2004-01-01

8 Organick, Elliott I.Semiannual technical report transformation of ADA programs into silicon (1 Sept. 1981- 28 Feb. 1982)This report summarizes the first six months work of the research project, "Transformation of Ada Programs into Silicon." Our project has five main objectives: 1. Develop and document elements of a transformation methodology for converting Ada programs, or program constructs, into VLSI systems which ...ADA programs; VLSI1982
9 Starkey, MikeSwitchbox routing by pattern matchingMany good algorithms have been designed that provide good solutions to the wire routing problem in VLSI. Unfortunately, many of these algorithms only consider a small subset of different parameters such as number of layers, routability of layers and technology. We believe that these algorithms can b...Switchbox routing; pattern matching; wire routing problem; VLSI1991
10 Harrison, Reid R.Validation of adaptive threshold spike detector for neural recordingWe compare the performance of algorithms for automatic spike detection in neural recording applications. Each algorithm sets a threshold based on an estimate of the background noise level. The adaptive spike detection algorithm is suitable for implementation in analog VLSI; results from a proof-of-...Spike detection; Neural recording; Ation potential; VLSI2004-01-01
