In contrast, a hardware interrupt can occur at any machine instruction, meaning an ISR can be activated at any point in the code. Such implicit activation is not synchronized with the main code, and ...

State machines help make seemingly large service routines short and simple to execute. There are a number of cases when decisions have to be made inside an interrupt service routine (ISR) and the ...

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 ...

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.

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

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 ...

Editor's Note: Linux remains an attractive option for embedded systems developers. In fact, industry surveys such as the Embedded Market Study by UBM (EDN's parent company) consistently show interest ...
