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 ...

The last part of the Embedded Systems programming discuss about interrupt processing and the alternative process of polling. It briefly describes interrupts and polling, as well as the interrupt ...

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, ...

Embedded TDD tests the logic that sits on top of your hardware and could reveal bad logic, with no hardware to muddy the diagnosis.

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 ...

Modern embedded systems are expected to operate with predictable timing, continuous reliability, and near-instantaneous response under increasingly complex workloads. From automotive control units and ...

Linux has taken the embedded marketplace by storm. According to industry analysts, one-third to one-half of new embedded 32- and 64-bit designs employ Linux. Embedded Linux already dominates multiple ...

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 ...
