ARM Cortex-A Interrupt Latency

ARM Cortex-A Interrupt Latency

In this article, I'll explore interrupt latency of a Cortex-A9 under various scenarios — and yes, it's still on the Zynq-7000, since I still have that board on my desk from the last two articles. An upcoming follow-up article will describe methods of improving worst case latency ... Read more

Embedded Storage on the snickerdoodle

This is a continuation of the snickerdoodle adventure, following last week’s successful “hello world” , using Micrium’s µC/OS RTOS. In this series of articles, I’m exploring the capabilities of the snickerdoodle as a development platform for high performance real-time operating systems. This time, I will be running an embedded file system on the snickerdoodle module, enabling non-volatile storage capabilities. The bare ... Read more

snickerdoodle says Hello World!

What would make a better first post about embedded software than a hello world project on a brand-new development board. It's the krtkl snickerdoodle I received with much excitement last week. In these next series of articles, I'm going to explore the capabilities of the snickerdoodle as a development platform for a high-performance real-time operating system. In this first article, ...
