As a silicon designer, ARM stands at least three steps back from the multi-billion unit embedded sensor/controller M2M market it would love to see driven by a booming Internet of Things (IoT). Problem: there are plenty of M2M standards and technologies but no core specification to give 'things' manufacturers the confidence to at least design a sensor/controller 'capability' in advance of connectivity demand... yet. Gary Atkinson, Director of Embedded Marketing at ARM, talks to Ian Scales about ARM's new forum tasked to hammer out a 'horizontal' specification.
