It’s no secret that I’m an advocate of edge-based computing, and after a number of years where cloud computing has definitely been in ascendency, the swing back towards the edge is now well underway. Driven, not by the Internet of Things as you might perhaps expect, but by the movement of machine learning out of the cloud.

Until recently most of the examples we’ve seen, such as the Neural Compute Stick or Google’s AIY Projects kits, were based around custom silicon like Intel’s Movidius chip. However, recently Arm quietly released its CMSIS-NN library, a neural network library optimised for the Cortex-M-based microcontrollers.
