Express Logic provides advanced, high quality software solutions for deeply embedded applications. The company was founded in 1996 by Bill Lamie, who did all of the initial products, including the ...

Interestingly, however, Embedded Research's Stewart points out that interrupts often do more harm than good in real-time systems. Most interrupt-driven systems, in fact, can be converted to one ...

A real-time system must respect time constraints to ensure that its execution makes functional sense. It must be deterministic, ensuring the execution of system processes a priori. After analyzing the ...

While the GNU/Linux Operating System is gaining popularity in research and student communities as well as in the business world, its impact is still limited for all those application areas requiring ...

As more complex devices with higher levels of integration are inserted into real-time systems, traditional testing methods are becoming obsolete. The most difficult obstacle to thorough testing of ...

In the last lesson, you encountered the concept of a Real-Time Operating System (RTOS), and you worked out a manual procedure of switching the context from one thread to another. In this lesson, ...

The proliferation of multicore processors has done more than provide a boost in processing power to server applications. Multicore chips also pose the opportunity to revolutionize how embedded systems ...

Learn the basics of embedded systems hacking with Arduino, Raspberry Pi & RTOS. Discover GPIO, interrupts, hands-on projects ...

In this fourth lesson in the Real-Time Operating System (RTOS) series, you’ll see how to replace the horribly inefficient polling delay with efficient thread blocking. Specifically, in this lesson 25, ...

Many real-time systems need a database. However, choosing one can be challenging depending on performance requirements. Why external consistency is so important for a hard real-time database.

Blood tests are among the most common tools in medicine. Scientists are working to make blood cell imaging faster and more ...
