Have you ever wondered what it takes to create a small system-on-chip (SoC) based on a Arm Cortex-M processor? In this blog, we explain typically what IP components are required and what other things you might need to put the whole system together.
Cortex-M in SoC designs: A history and a future
Since the Cortex-M0 processor was released a few years ago, the number of silicon designs based on Cortex-M processors has increased substantially. By the end of 2016, it was reported that there were over 400 Cortex-M licensees, with most of these licensees using Cortex-M processors in non-MCU products.
In fact, Cortex-M processors are finding their ways into new SoC designs whose previous generations did not include a Cortex-M, let alone a digital processor core. As a result, many SoC design engineers have taken the exciting journey of integrating a Cortex-M processor core for the first time without previous experience or any knowledge of important considerations required.
Integrating Cortex-M FAQs: A white paper
This white paper seeks to answer some of the frequently asked questions SoC designers face when integrating a Cortex-M processor for the first time. At the end of this white paper you will find a host of links to other resources and information that will be of use.
Since this is a big topic to cover, I am sure there is some information I missed. If you have additional information which can be useful to other chip designers, or if you spot any error in this document, please contact me and I will update this document from time to time.
