Software Reliability and the Internet of Things

 Printable PDF

As Internet connectivity advances, the transportation, automotive, medical device, smart grid and other industry sectors have become more dependent on embedded software. But is embedded software up to the required level of reliability?

How to Find and Fix the Most Common Embedded Software Bugs

As if debugging traditional PC/server software or even smartphone apps wasn't hard enough, debugging embedded software adds significant challenges. This webinar introduces you to some of the most common embedded software bugs and teaches you how to find/fix/prevent them.

How to Secure Consumable Components of Medical Devices and Other Embedded Systems

 Printable PDF

A number of embedded systems, such as medical devices and printers, feature replaceable components designed to be installed new, consumed through one or more cycles of product use, and ultimately disposed. This article describes the security challenges associated with the design of such consumable components as well as practical solutions.

Mutexes and Semaphores Demystified

What's the difference between a mutex and a semaphore? Even very experienced firmware developers too often fail to fully appreciate the importance of using the correct tool for the job at hand. And, unfortunately, misuse of these two distinct types of synchronization primitives can lead to difficult to debug defects in embedded software, with potentially severe consequences in safety-critical medical devices, avionics and transportation equipment.
