EE Journal - Embedded FPGA ASIC Design

Embedded Technology Journal and FPGA Structured ASIC Journal are now in EE Journal

EE Journal - Embedded  FPGA ASIC Design
"The first year of a new publication is always exciting, but Embedded Technology Journal first year has been nothing short of stellar. We began, of course, with modest-sized audiences mulling our strange stories about putting tiny little computers into toasters and such. People pondered processors, studied software, meditated about memories, brushed up on busses, wrestled with RTOS, and fumbled with FPGAs. We covered applications ranging from smart phones to avionics and touched on some truly unique systems like golf radar and digital scarecrows."

An approach to comprehensively verify a multi-clock design

"One example of a combined solution is outlined in Figure 2, where timing exceptions between synchronous clocks are verified using Atrenta’s SpyGlass-TXV timing exception verification tool and the correct synchronization of interfaces between asynchronous clocks is handled by the SpyGlass-CDC tool, giving complete overall coverage."

LightRadio Antenna Module

LightRadio Antenna Module

"Tod Sizer, Head of Wireless Research for Alcatel-Lucent Bell Labs, talks about developing the lightRadio antenna module. lightRadio represents a new architecture where the base station, typically located at the base of each cell site tower, is broken into its components elements and then distributed into both the antenna and throughout a cloud-like network...."

Touchstone Semiconductor - Analog IC Solutions

The Product Range include Amplifiers, Analog to Digital Converters, Comparators, Current Sense Amplifiers, Timers, Voltage Detectors and Voltage References.

micropower solar-harvesting application
"You can use the circuit in a micropower solar-harvesting application (Figure 3). Depending on the light, the BPW34 cells generate 10 to 30 µA at 0.8 to 1.5V. The active-diode circuit rectifies the peak harvested voltage in conditions of rapidly changing light and minimizes reverse leakage to the cells."

SCADA - Supervisory Control and Data Acquisition

A Closed loop control system has a Sensor-Controller-Actuator. The Bimetal Thermostat has all the three in the Bimetal itself. The Sensor, the Relay Contact and the Intelligence. This is Process Control when implemented to control the temperature in a Bakery Oven.

This leads us to Sensors-Transmitter-Controller-Outputs-Actuators. Where each is an independent electronic/electrical component of an entire Process Control system. The Process could be Temperature, Pressure, Speed, or Level.

IntegraXor SCADA

IntegraXor SCADA  - Create the interactive graphical interface for multi-device compatibility.

Industrial Automation encompasses many such Process Control Systems to form a Engineered System Solution for an Entire production line with different stages and process types.

At the machine end, the control has to be real time and highly reliable, dedicated controllers both Analog and Microcontrollers based are used. Analog as a fallback/override/trip or backup controller in case Embedded system gets stuck/fails.

These controllers or transmitters also send the data of the process back to a center control panel room. The actuators and outputs also have an override from the control panel. Sometimes Intelligent controllers at machine end can be remotely tweaked/tuned by Control room. This is possible due to Embedded systems and Flash., It also can pose problems if misused. Using SCADA such networking of these process control systems and Monitoring, Tweaking, Data Collection and Analysis is possible.

Come Internet or Web and Wireless, the scenario changes entirely. The Control room stays where it is, the Tablets can Access and utilize the SCADA and entire plant at the machine end also. The Control room can be carried around with limited access. This evolves further to that extent that an expert engineer can check the status of the Product Line from any Web Browser and suggest remedial actions to the others at the factory. He can even see the status on mobile devices. Now study the Resources below.

Industrial Process parameters, production flow or work status, material offtake, processing of products, incoming inspection status and quality process monitoring. All these need to be interfaced with the ERP and access to Mobile devices like Smartphones and remote Computers provided. This helps smooth micro management of a industry. Some Interfaces may have supervisory control and others just graphs and progress charts. Depending on the person and his work or machine area.

The data and presentation of complex data (by graphs and charts) enhances analysis and timely decision making. Then these solutions will be productive, and be an asset to an existing system. To ensure that; software or webware developers have to be supported by the domain experts having decades of hands on experience on the shop floor. Else; if it is built on theory and some statistics, the result may appear good and work well for small or standard configurations, but in demanding, changing, real life scenario, it may fail to deliver the best.
