Embedded Design During Chip Shortages

Dave Hughes - TUXERA - Watch Now - Duration: 28:05

In these modern times of chip shortages, the need for flexibility and portability in the design of embedded products has been pushed to center stage. There are three main factors that tie your development to a particular microcontroller: the RTOS, the toolchain, and the peripheral controllers. This presentation describes the embedded development practices Tuxera uses to free users of microcontroller dependency, in order to make their software solutions portable – an absolute must for an embedded software company. Your product expertise should not be held hostage to the global supply chain problems. By making good design decisions early in the development process you can make it easier to move to alternative architectures when unexpected supply chain issues appear.

Abstracting the RTOS was the most interesting section, that is one area I didn't consider for chip shortages! Thanks for sharing your knowledge in that area.

Thank you Dave, for your presentation. Will you be publishing your slides here?
I've pitched a similar framework before -- before 'Supply Chain Issues' was a thing -- so your talk is resonating well with me. Thank you for your consideration.

Hi Nathan, I really liked the talk! Thank you very much!
One initiative achieving a level of abstraction for ARM is CMSIS - what is your experience with /take on CMSIS?

Hi Andreas, I think we covered this a bit in the live Q&A - but in short - if you are wedded to ARM (or more accurately the supported Cortex types) - then it is a very comprehensive abstraction and as long as you can get conformant drivers for your target it must be an important option. For us it did not work because we needed our components to run on any architecture - but we have abstractions to CMSIS (and in particular the RTOS) for our components.

Thanks for the presentation, very interesting.
At my company we are seeing more and more customers asking us to port their firmware to new microcontrollers. The difficulty of those migration projects highly depend on the abstraction you describe in your video.
Also, could you publish the slides ?

Very interesting talk!
I think pretty much everybody today is minimally aware of the risks associated with non-portable code and some basic strategies like a set of primary software design principles, and the use of language usage constraints like MISRA. Today, however, with the increasing shortage problems, these risks have become more probable than ever,. and developing without minimum portability in mind is pretty much suicidal. In addition, the rise of embedded software complexity and off-the-shelf software and development ecosystems provided by silicon vendors with a certain degree of lock-in provides a lot more of coupling surface increasing the effort of making it portable, making careful planning and designing more necessary than ever.
What I enjoyed most about the talk though is the ability to structure and summarize the main challenging aspects and tactics to overcome them with success that the talk is able to distill.

Well-said Dave. Very good guidelines to follow that could save many projects from all the different kinds of crises that could cause a need to change MCUs to meet demand.
