It appears Ultrasoc has some hardware-level diagnostic abilities that will be interesting to some:

“Our products allow engineers to look inside systems-on-chip (SoCs) during the development process, and understand exactly how they operate under real-life conditions. Development teams are using our on-chip monitoring and analytics IP to equip their SoCs with an exciting range of new capabilities, applicable in markets from network infrastructure to mobile phones, and from safety-critical systems to the Internet of Things (IoT). These include value-add functions such as service level agreement (SLA) enforcement and in-service performance enhancement – functionality enabled by chips with hard-wired self-monitoring capabilities. UltraSoc’s “smart” modules operate across the whole SoC: reporting rich information in real-time, non-intrusively, from hardware and software. And because the system is vendor-neutral, it provides an efficient way to integrate IP from different vendors, into one coherent framework, including legacy solutions or in-house custom logic.”
