VISION BASED PROCESSING FOR REAL TIME 3-D DATA ACQUISITION BASED CODE STRUCTURED LIGHT-IMAGE PROCESSING

Abstract: The structured light vision system is a successfully used for the measurement of 3D surface in vision. There is some limitation in the above scheme, that is tens of picture are captured to recover a 3D sense. This paper presents an idea for real-time Acquisition of 3-D surface data by a specially coded vision system. To achieve 3-D measurement for a dynamic scene, the data acquisition must be performed with only a single image. ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

This article describes a DDR SDRAM (Double Data Rate Synchronously
Dynamic RAM) controller. The commands of the FPGA-based DDR
SDRAM controller is described in detail. The Verilog HDL is used to implement the R/W operation of the DDR SDRAM. This controler isused to control a 400MHz single channel high-speed, high-precision and large-capacity data acquisition board.

Introduction
The speed and precision of data acquisition system must be sufficiently high to meet the requirements of advanced communication technology development. h ....etc

HIGH-PERFORMANCE DSP CAPABILITY WITHIN AN OPTIMIZED LOW-COST FPGA ARCHITECTURE

ABSTRACT
The applications of Digital Signal Processing (DSP) continue to expand,
driven by trends such as the increased use of video and still images
and the demand for increasingly reconfigurable systems such as Software
Defined Radio (SDR). Many of these applications combine the need for
significant DSP processing with cost sensitivity, creating demand for
high-performance, low-cost DSP solutions.
General-purpose DSP chips ....etc

Data Acquisition and Data Logging



What is data acquisition and data logging
Data acquisition is simply the “gathering of information about a system or process”
Information may be gathered for various reasons
knowledge
research and development
systems or process monitoring
systems or process control
Data acquisition requires one or more transducers (sensors) to sense the system or process, and a signal measuring instrument

What is data ....etc

Abstract
A data acquisition system was developed as a final project for the microcontroller design course at UW-Platteville. This system was developed to monitor power supplies and aid as a development tool for the design of a 200 W switch-mode power supply. A PIC microcontroller from Microchip was used as the heart of the data collection system. Internal analog to digital converters acquired data from an analog interface. The analog subsystem gathered data from temperature, voltage, and current sensors. Data was re ....etc

High-Throughput Low-Cost AES Processor


Chih-Pin Su, Tsung-Fu Lin, Chih-Tsun Huang, and Cheng-Wen Wu, National Tsing Hua University


ABSTRACT

We propose an efficient hardware implementation of the Advanced Encryption Standard algorithm, with key expansion capability. Compared to the widely used table lookup technique, the proposed basis transformation technique reduces the hardware overhead of the S-Box by 64 percent. Our pipelined design has a very high throughput rate. U ....etc
