After introducing interrupts and the foreground/background architecture, I am finally ready to tackle the concept of a Real-Time Operating System (RTOS). In this first lesson on RTOS (commonly ...

Different tasks in an embedded system typically must share the same hardware and software resources or may rely on each other in order to function correctly. For these reasons, embedded OSs provide ...

Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...

Heterogeneous multiprocessor (HMP) systems, using functionally asymmetric compute elements, such as application processors and microcontrollers integrated within the same SoCs, are now used ...

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 ...

With the advent of multithreaded/multicore CPUs, even embedded real-time applications are starting to run on SMP systems—for example, both the Xbox 360 and PS/3 are multithreaded, and there even have ...

As embedded systems hardware is becoming more powerful, the demand for high quality, sophisticated and compelling applications is increasing. In addition to that, due to fierce competition in the ...
