A field-programmable-gate-array-(FPGA-) based data acquisition and control system was designed in a hardware/software codesign environment using an embedded Xilinx Microblaze soft-core processor for use with a subsurface ion mobility spectrometer (IMS) system, designed for detection of gaseous volatile organic compounds (VOCs). An FPGA is used to accelerate the digital signal processing algorit...

This paper deals with the implementation of PID controller for a DC motor controller application on FPGA platform. The soft IP core of PID controller is implemented on FPGA ALTERA Quartus II platform by using Quartus II software version 10.1. The PWM signal is generated by ALTERA board, which further given to DC motor for its speed control. The soft IP core of PID controller is prototyped and v...

This paper presents an application of LabVIEW graphical programming and FPGA technology in the area of sensor calibration. A water quality sensor calibrator based on compact reconfi gurable FPGA core that works under a real-time controller is described. The system provides automatic calibration of stand alone sensors such as turbidity, pH or conductivity using diff erent calibration solutions t...

Two common problems we face in implementing reconngurable 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 speciications. One solution to address the rst problem is partial reconnguration or run-time recon-guration which requires only loading a portion of the desi...

The scientific community has been using FPGA-based computation engines as cellular automata (CA) accelerators for some time now. With the recent advent of more advanced FPGA logic it becomes necessary to better understand the mapping of CA to these systems. In this paper, we present a methodology to predict the performance of running such CA on specific FPGA hardware before engineering the desi...

Decreasing cost and increased complexity of modern field programmable gate array (FPGA) devices, such as Xilinx’s Spartan 3[1], have allowed the development of true system on a chip (SOC) architectures for embedded micro-controller and ubiquitous computing applications. To minimize the size and, therefore, the cost of the required FPGA, consideration must be given to matching the desired functi...

Unlike other integrated circuits, SRAM-based FPGA devices present a unique problem for testing. Because of their high level of configurability, it is often difficult to isolate and test device resources. This high level of configurability of FPGA devices, while a drawback for traditional test methods, can also provide unique advantages when performing device test. If configurability is used to ...

Abstract—This paper presents an architecture for a reconfigurable device which is specifically optimised for floating point applications. Fine-grained units are used for implementing control logic and bit-oriented operations, while parameterised and reconfigurable word-based coarse-grained units incorporating word-oriented lookup tables and floating point operations are used to implement datapa...

Field programmable gate arrays (FPGAs) provide an attractive solution to developers needing custom logic for short time-to-market products. Products embedding FPGA system-on-chip solutions have the advantage in that they can be updated once deployed. New FPGA firmware may be loaded via manufacturer-supplied memory devices or remotely via a network connection. Recent FPGAs allow for self-reconfi...
