Diseño CMOS de un sistema de visión “on-chip” para aplicaciones de muy alta velocidad [PhD Thesis]
(2016-02-08)
Esta Tesis presenta arquitecturas, circuitos y chips para el diseño de sensores de visión CMOS con procesamiento paralelo embebido. La Tesis reporta dos chips, en concreto: El chip Q-Eye; El chip Eye-RIS_VSoC.. Y dos ...
Learning under hardware restrictions in CMOS fuzzy controllers able to extract rules from examples [Article]
(Universidad de Granada. Departamento de Ciencias de la Computación e Inteligencia Artificial, 1996)
Fuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are no experts or/and rules are not easy to find. Author's ...
A 2.5MHz 55dB Switched-Current BandPass ΣΔ Modulator for AM Signal Conversion [Presentation]
(Institute of Electrical and Electronics Engineers, 1997)
We present a Switched-Current (SI) fourth-order bandpass ΣΔ modulator IC prototype. It uses fully-differential circuits in 0.8μm CMOS technology to obtain a Dynamic Range (DR) larger than 55dB at 2.5MHz center frequency ...
A 176x144 148dB adaptive tone-mapping imager [Presentation]
(Society of Photo-Optical Instrumentation Engineers, 2012)
This paper presents a 176x144 (QCIF) HDR image sensor where visual information is simultaneously captured and adaptively compressed by means of an in-pixel tone mapping scheme. The tone mapping curve (TMC) is calculated ...
High-order cascade multi-bit Σ∆ modulators for high-speed A/D conversion [Presentation]
(Universidad Carlos III, 1998)
The use of Sigma-Delta (Σ∆) modulation for analog-to-digital conversion (ADC) in the communication frequency range is evaluated. Two high-order multi-bit architectures are proposed to achieve +12-bit dynamic range at ...
A CMOS vision system on-chip with multicore sensory processing ar- chitecture for image analysis above 1,000F/s [Presentation]
(Spie, 2010)
This paper describes a Vision-System-on-Chip (VSoC) capable of doing: image acquisition, image processing through on-chip embedded structures, and generation of pertinent reaction commands at thousand’s frame-per-second ...
High dynamic range adaptation for ROI tracking based on reconfigurable concurrent dual-sensing [Article]
(Institution of Civil Engineers (Great Britain), 2014)
A single-exposure technique to extend the dynamic range of vision sensors is presented. It is particularly suitable for vision algorithms requiring region-of-interest (ROI) tracking under varying illumination conditions. ...
Diseño de chips programables de señal mixta con bajo consumo de potencia para sistemas de visión en tiempo real [PhD Thesis]
(2002)
Las Tecnologías de la información y de las Comunicaciones han progresado de forma vertiginosa durante los últimos años. Los laptop actuales tienen prestaciones similares o superiores a las de las estaciones de trabajo de ...
A hierarchical approach for the symbolic analysis of large analog integrated circuits [Presentation]
(IEEE computer society digital library, 2000)
This paper introduces a new hierarchical analysis methodology which incorporates approximation strategies during the analysis process. Consequently, the circuit sizes that can be analyzed increase dramatically, ...
