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 ...

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 ...

The proper use of an embedded MCU's low-power/sleep modes is critical to a design's success. In today's world of battery-operated devices, the proper use of the low-power/sleep modes provided in most ...

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

Callbacks are references to executable code that higher levels of software pass into a function. These callbacks have the ability to greatly increase the portability and reuse of embedded software, ...

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 ...

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.

There's an interrupt service routine invoked when the 16 bithardware timer overflows. The ISR services the hardware, increments aglobal variable named timer_hi, and returns. Therefore, timer_hi ...

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 ...
