How to Prioritize RTOS Tasks (and Why It Matters)

Presented by Barr Group Principal Engineer Salomon Singer, this webinar examines best practices for assigning fixed priorities to a set of real-time operating systems (RTOS) tasks and interrupt service routines (ISRs). Viewers will learn how and why to use optimal methods to allow a critical set of tasks and interrupt service routines to meet all of their deadlines – even during transient overload periods. Lessons learned can be applied to the development of any priority-based preemptive RTOS, including real-time Linux.

Top 10 Causes of Nasty Embedded Software Bugs

Finding and killing latent bugs in embedded software is a difficult business. Heroic efforts and expensive tools are often required to trace backward from an observed crash, hang, or other unplanned run-time behavior to the root cause. In the worst case scenario, the root cause damages the code or data in such a subtle way that the system still appears to work fine or mostly fine-for some time before the malfunction.

How to Allocate Dynamic Memory Safely

Whether you're using only static memory, a simple stack, or dynamic allocation on a heap, you have to proceed cautiously. Embedded programmers can't afford to ignore the risks inherent in memory utilization.

Every program uses random access memory (RAM), but the ways in which that memory is divided among the needy parts of the system varies widely. This article surveys the options available in hopes that the reader will be better equipped to choose an approach for a given project.
