How to Determine Flow Totalization Utilizing Analog Ethernet I/O App Note

Flow Totalization Utilizing Analog Ethernet I/O Defining the Problem: A municipality wants to monitor water usage and does not have the capability to scale analog data. They want an all-in-one solution which will read, scale, and totalize the inputs from the flow meters. System Requirements: Flow meters producing a DC current (±20mA, 0-20mA, 4-20mA) or…

How to Monitor a Remote Geothermal Steam Well for Power Generation App Note

Defining the Problem: Operations at a remote geothermal steam well are monitored by a PLC from the power plant. C&I personnel need to transmit conditions from the wellsite to the control room 2km away. A wireless communications network is available for Ethernet remote I/O. The modules can be installed at the wellsite for telemetry purposes….

How PMC FPGA Boards Excel at Image Processing Application Note

Acromag has engaged in a number of image processing applications based upon implementations of Camera Link running on a Virtex-5 FPGA module. In several of these instances, LVDS signals are used to collect the image data through front and/or rear I/O connections on the PMC FPGA module. Other applications use a custom interface developed for…

FPGAs Go Green with Wind Turbine Control App Note

Energy conservation is ever-growing in importance, both from environmental and personal perspectives. Using less energy will preserve resources and reduce consumer costs provided appropriate low-energy devices are made available, reliable, and put into commonplace use. Successful green power generation requires that: a) more power is produced than is consumed in generating the power, and b)…

How to Get the Timing Right in Critical FPGA Applications Application Note

As the capacity of FPGA devices increases, the quantity and complexity of application tasks deployed on a single PMC FPGA module likewise increases. As a result, accurate management of all the unique clocks associated with these tasks becomes a very significant challenge for the application developer. In this article, we discuss the tools and constructs…

How to Reduce Costs with Customized I/O on COTS FPGA Modules App Note

It is now common to deploy COTS FPGA modules to help speed development cycles and reduce overall project costs. However, to maximize savings when FPGAs are used to perform custom I/O functions, it is very important to first determine the suitability of a particular FPGA module for the application. This determination is dependent upon several factors: The…
