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 ...

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 ...

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 ...

This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

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

Potentially substantial performance gains from the use of multithreading and multiprocessing architectures have captured the attention of designers of consumer devices and other electronic products.

A new breed of micropro-cessor based on very long instruction word (VLIW) technology is well suited for embedded systems. This is due to the fact that VLIW architectural simplicity is achieved at the ...

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 ...
