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 ...

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 ...

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 ...

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.

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 I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications ...

Today’s sophisticated vehicles leverage embedded systems for everything from infotainment to powertrain management. Even low-end automobiles incorporate scores of electronic control units (ECUs). By ...
