Model based testing (MBT) claims to shorten schedules, reduce cost and ensure better quality. So it's worth taking a close look at this methodlogy. To guide you, Peter Mueller provides an overview of MBT on state machines designed for used in a sump programmable logic controller.
How should processes running on different RTOSes communicate in systems with more than one operating system? The author suggests you can manage inter-process communications with global-object networking.
According to Rob Oshana and Stuart Yoder of Freescale, while virtualization enables the sharing of hardware resources on a single computer system, allowing multiple OSes to simultaneously share the system, the trick is picking the use case that best matches your application.
Bill Graham reviews some of the security best practices that embedded systems need to pay attention to in their designs, particularly those requiring the use of real time embedded operating systems (RTOS)in mission and safety critical systems used in industrial and medical devices.
In this first part of a two-parter, the Filter Wizard – aka Kendall Castor-Perry – looks at some fundamental facts about FIR filter responses, using some basic math you might even remember from school.
The choice of an RF or microwave power measurement system is more complex than ever with the recent availability of new functions in power meters previously reserved for higher-end analyzers. With the large variance in product offerings and specifications on manufacturer's data sheets, it's helpful to have an understanding of the most important factors when evaluating USB power sensors/meters.
Here's Part II of User Interface—The next battlefield. In the next phase of UI adoption, rather than require user training, devices with advanced UIs will need to adapt to consumers so they can be used “out of the box”. To achieve this, devices need to become more intelligent and, as such, will require more processing power and memory.
Phase change memory (PCM) faces real issues in scaling to the 20-nm node and beyond, but innovative structures and materials may help the technology fight off the flash memory challenge.
