The very first step in starting an embedded Linux system does not involve Linux at all. Instead, the processor is reset and starts executing code from a given location. This location contains a ...

With multicore embedded systems becoming so common, this article outlines some of the basics, reviewing the possible hardware architectures. Broadly, there are two options: Asymmetric Multi-Processing ...

This course is used as the capstone in a three course sequence, including Linux System Programming and Introduction to Buildroot and Linux Kernel Programming and Introduction to Yocto Project. Both of ...

Microcontrollers have proliferated into every nook and cranny of our daily lives from simple 8-bit devices that control our toaster ovens to powerful 32-bit DSPs that provide us with the rich media ...

Despite the hopes and dreams of many embedded engineers, reliable code doesn’t happen by accident. It is a painstaking process that requires developers to maintain and manage every bit and byte of the ...

Thomas Herbert's book The Linux TCP/IP Stack: Networking for Embedded Systems is a thorough guided tour of the Linux kernel TCP/IP implementation. Herbert builds his description of Linux networking, ...

And, finally, there’s an article on minimizing complexity with MEMS-based clock generators. As more advanced systems become ...

Counter/timer hardware is a crucial component of most embedded systems. In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a ...

In the previous blog post, “Securing Offload Engines for a Robust Secure SoC System,” we briefly looked at some of the methods employed for achieving embedded security, i.e., cryptography, hardware ...
