How to Make Embedded Software Smaller and Faster

Many embedded systems have reliability, cost, and performance requirements that demand performance be designed into the system, from architecture to algorithms to data structures to coding guidelines.

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.

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? Misuse of these two distinct types of synchronization primitives can lead to difficult to debug defects with potentially severe consequences in safety-critical devices.

Pros and Cons of AndroidOS for Embedded Systems

Android software architecture, hardware requirements, licensing terms, and security considerations with a few case studies to illustrate the pros and cons of building embedded systems around the AndroidOS.

Hardware-Software Partitioning in Embedded Systems

One of the biggest challenges when architecting an embedded system is partitioning the design into its hardware and software components, which must typically be decided early in the design of a product.

Key Learnings from Past Safety-Critical System Failures

Welcome to the 21st century, where every device has at least one processor. But don't take for granted that these devices will do their intended jobs tirelessly and correctly, day in and day out, without fail.

Top 10 Bug-Killing Coding Standard Rules

To increase security and keep bugs out of medical devices and other safety-critical embedded systems, add these 10 bug-killing rules to your embedded C coding standard.

Killer Apps: Embedded Software's Greatest Hit Jobs

As embedded software's size and complexity continue to rapidly progress, user safety increasingly relies upon safe and reliable firmware implementations. Barr Group co-founder and CTO Michael Barr presents an engaging discussion of the past, present, and future of embedded software safety. 

How to Minimize Interrupt Service Routine (ISR) Overhead

With all the automation available today, it's easy for programmers to overlook costly overhead introduced into machine code by the compiler. Interrupt handlers are one key area worthy of a closer inspection.
