Hardware virtualization, and the hypervisors that enable it, have become a hot topic in the embedded space. But while virtualization opens up new possibilities for system architects and designers, it also poses new challenges, especially when used with real-time applications.
Designing Custom, Low-Cost Instrumentation for Test and Measurement Using Off-the-Shelf FPGA ModulesApril 29, 2010 11:36 am | by Jake Janovetz, Opal Kelly | Comments
Designing for industrial applications presents many challenges, but it also allows an engineer to be creative, spread her wings, and explore new technologies to solve the task at hand. Field-Programmable Gate Arrays (FPGAs) and, in particular, commercial off-the-shelf (COTS) FPGA modules can be just the ticket to attack industrial applications that used to be a much more difficult challenge.
Industrial applications, such as home and commercial building automation, data loggers, point-of-sale terminals and cash registers, in-house displays for energy metering, alarm systems and medical equipment are starting to join the “smart” revolution currently enjoyed by portable media player and smartphone markets.
Monitoring the condition of large industrial machinery provides long term benefits in terms of lower production cost, reduced equipment down time, improved reliability, and increased safety. Industrial manufacturers face a constant battle in keeping production equipment operational.
What future technologies will reduce healthcare costs?
Is breadboarding dead?
There seems to be no end to the demand of higher data rate applications and performance requirements as the number of new mobile devices continues to increase dramatically. The usage of mobile devices has evolved from voice only to multimedia messaging, downloading emails, web browsing, online gaming, video calls, social networking etc.
A pop musician recently reminded me that hit songs aren’t only catchy tunes; they are also a barometer of culture. I never expected to refer to Lady Gaga with anything other than casual references to her music or her edgy style (I’ve heard it called “21st-century Madonna), but one of her recent songs gave me some pause.
In March the Associated Press ran a story about security vulnerabilities in smart meters based on the research of InGuardians, Inc. The article highlighted the Achilles heel of any secure wireless system; the inadequate safeguarding of the security keys themselves.
LCD displays are widely used in cell phones, personal media players, internet tablet PCs, laptops, and large-screen TV sets. These displays account for a major part of the power consumed by these devices. For example, a mobile phone screen may consume upwards of 40% of the system power, while in a large-screen TV, the display may consume 70% or more of the system power.
The touchscreen is rapidly becoming the user interface technology of choice in applications ranging from retail, industrial and automotive, to medical, digital signage and gaming. Their growing popularity has been fuelled in part by the phenomenal success of the iPhone and its highly user-friendly, all touchscreen controls...
Despite the potential hazards of ultraviolet light, the UV spectrum is proving to have many beneficial effects in a multitude of areas, offering a wide range of advantages to a diverse number of applications.
Digital video recorders (DVRs) take the analog video input from closed circuit televisions (CCTVs), digitize the input using video decoders and then compress this digital data before storing it on a local storage media like hard disk. The critical advantage that DVRs give over tape-based predecessors is that one can process the recorded data much better and perform event search, time search and more to play back specific content.
As a teenager, I built many "computer" circuits with relays and switches. As I recall, a flip-flop took two 2PDT relays and a binary adder took two 4PDT relays in my brute-force logic circuit. Kids today can get started exploring computers more easily.
Electrocardiogram (ECG) system analog front-end (AFE) devices are typically designed with discrete off-the-shelf components from various semiconductor vendors. The primary components of a traditional discrete ECG AFE include instrumentation amplifiers, operational amplifiers that implement active filters, and analog-to-digital converters (ADCs).
