This paper presents the architecture and implementation of a real time adaptive NLMS filter for nonstationary noise cancellation in a car environment.The active noise control techniques using adaptive digital filters are very much suitable and well proven.The proposed efficient Adaptive Noise Canceller is realized using Xilinx System Generator 12.3 on Spartan 3E FPGA. System Generator is a DSP ...

Existing FPGA architectures can be classified along two dimensions: reprogrammable vs. one-time programmable and general-purpose vs. domain specific. The most challenging class of FPGA architectures to design is the reprogrammable, general-purpose FPGA, of which Xilinx is the most wellknown example. In this paper we describe Triptych, a new FPGA architecture that addresses two problems of curre...

Area optimization is one of the important problems in reconfigurable systems. A Field-programmable gate array (FPGA) based optimised Fuzzy Logic Controller(FLC) has been developed for speed control of DC Motor by exploiting the basic features of Fuzzy logic. The aim of the proposed scheme is to reduce the area, as compared with conventional Fuzzy Logic Controller. The area of a design refers to...

Two common problems we face in implementing recon gurable systems on currently available FPGA chips are: (1) tting designs which are too big for available hardware resources on a single FPGA chip, (2) lack of synthesis tools for high-level speci cations. One solution to address the rst problem is partial recon guration or run-time recon guration which requires only loading a portion of the desi...

The rapid advances in very large scale integration (VLSI) technology lead to implement modern high speed digital controllers with excellent performance, compared to traditional analog control systems. The field programmable gate array (FPGA) devices provide programmable system-on-chip (SoC) environments for designing powerful ASIC controllers with dedicated architectures. This paper presents a ...

The article presents FPGA-based hardware platform for executing control system software written in languages of IEC 61131-3 standard in CPDev integrated development environment. Supported data types, compilation to intermediate code and two implementations of FPGA execution machine – basic and enhanced are described. The implementations have been tested for speed and compared with software-base...

The requirement for short time-to-market has made FPGA devices very popular for the implementation of general purpose electronic devices. Modern FPGA architectures offer the advantage of partial reconfiguration, which allows an algorithm to be partially mapped into a small and fixed FPGA device that can be reconfigured at run time, as the mapped application changes its requirements. Such a feat...

هدف این تحقیق طراحی و سنتز پردازنده فازی آستانه گیر تصویر دیجیتال با زبان سخت-افزاری vhdl و به منظور پیاده سازی بر روی تراشه fpgaاست. در ابتدای این پژوهش چند الگوریتم آستانه گیری تصویر مورد بررسی قرار گرفت که از بین آنها الگوریتم آستانه گیری مبتنی بر مجموعه های فازی برای پردازنده مورد نظر انتخاب شد. این الگوریتم برای تصاویر با کنتراست پایین به خوبی عمل نمی کرد که برای این منظور یک راهکار ارائه ...

In this paper, an integrated hardware and software design method is developed to implement an MPC algorithm on an FPGA chip. This makes it possible to achieve the long-desired goal of extending MPC algorithms to field control so as to deal with constraints effectively. To expedite the numerical procedure of solving quadratic programming (QP) in the MPC algorithm, a QP solver based on embedded c...
