Programming embedded systems: Introduction Programming embedded systems: What are interrupts, and how they work Programming embedded systems: Startup code and the world before main() Programming ...

As mentioned in previous chapters, the architecture determines the interrupt model of an embedded system (that is, the number of interrupts and interrupt types).

Interrupt distribution unit (shared) See Figure 3 below for the system design options. Figure 3: Two system design options for interrupts, for example with Arm Cortex-A and Cortex-M processors 3. How ...

Editor's note: In this first part in a series on the appropriate use of interrupts in embedded systems design , Priyadeep Kaur of Cypress Semiconductor starts with general guidelines and good ...

An embedded pSOS-based application is partit ioned into a set of tasks and interrupt service routines. Each task is a thread of independent actions that can execute concurrently with other tasks.

Conventional applications overcome this problem by briefly locking out interrupts while an ISR or system service modifies crucial data structures.

This simplifies PCB design and enables more scalable systems. The addition of In-Band Interrupts (IBI) removed the need for external interrupt lines and allows targets to raise interrupts over 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 ...

SystemView is a real-time recording and visualization tool that’s been designed to analyse and provide deep insight into the runtime behaviour of embedded systems. It offers a different perspective on ...

Using multiprocessing and multithreading architectures together helps generate higher performance in a range of applications.
