International Review on Computers and Software

This paper presents an image processing system based on smart camera platform, whose two principle elements are a Wide-VGA CMOS Sensor and a Field Programmable Gate Array (FPGA). The latter is used to control the various sensor parameter configurations and, where desired, to receive and process the images captured by the CMOS sensor. With the advent of today's highly integrated Field Programmable Gate Array (FPGA) it is possible to have a software programmable processor and hardware computing resources on the same chip. Apart from having sufficient logic blocks on which the hardware is implemented these chips also have an embedded processor with system software to implement the application software around it. In this paper, the Spartan-3A DSP based Xilinx VSK platform is used for developing the proposed extensible hardware-software video streaming and processing modules. In order to develop the required hardware and software in an integrated fashion, Xilinx Embedded Development Kit (EDK) design tool has been used. A number of Xilinx provided IPs are customized to realize the hardware modules in the FPGA fabric. © 2013 Praise Worthy Prize S.r.l. - All rights reserved. Source

International Review of Electrical Engineering

In this paper, we present a design method of Direct Torque Control based on hardware description language and FPGA implementation. The DTC, which is used to control induction machines, is designed through the description of Concordia transformation, torque and stator flux estimator, torque and stator flux comparator, stator flux position detector, switching table and Finite State Machine (FSM). The same algorithm is designed and simulated using MATLAB software tool to make a comparison with the proposed design on FPGA. Experimental test results of this drive control structure realized in FPGA are demonstrated. © 2013 Praise Worthy Prize S.r.l. - All rights reserved. Source
