T L S . . agreed . . Partitioned to be self contained but integrated to function at its optimum without degradation of capability especially in Mission Critical Systems such as seat belts and braking.
In the olden days, there wasn't much electronics in cars, then gradually more features got added and each was stand alone. Recently there may have been up to 50 ECUs in a car (tiny computers) each for only 1 or two functions. This adds to the weight, cost, wiring and installation time.
Now forward thinking car companies are addressing this problem head on, now more of the devices are being centralised into fewer and fewer "computers" each looking after a particular "domain"
So you have a core "safety" one that controls braking, steering etc This needs to work ALL OF THE TIME!!!
You have an ADAS one that looks after the cameras and the secondary features, These supervise driving, so if they fail, it won't kill you, but when you need them, you need them - like a safety belt - this needs to work 99.99... % of the time.
and you have the infotainment systems - annoying when they don't work, but shouldn't kill you if they do. These ought to be working 99 % of the time (and boy to people get grumpy when they don't work - this is why certain companies get a poor reputation)
The Arm announcement is about a series of new chip "designs" that have better performance, have better ASIL safety ratings (they are trusted better for Safety features) and have partitioning, so that you can run multiple systems on the same hardware - if one fails (let's hope it was infotainment) it will not affect your ADAS or primary safety systems.
The Arm announcement included a quote from a head honcho at VW
VW need this because they are well on the way to merging their ECUs onto fewer devices and have even restructured all of their software development teams into one organisation to support this.
Good thing too that we have devoted so much time and effort to ensure our code runs really well and is optimised for power, memory and speed on Arm!
Whatif
Just another one to throw in the mix. We will end up with licenses with most anyway so atm its only who declares 1st.
When we know the 1st one the others wont be far behind iam sure.
Terry - Are you thinking the MOU may be with ARM?
Add another to the list of Whodunit...
Arm’s new Mali-G78AE GPU provides flexible partitioning for up to four independent partitions for separate safety workloads. For example, an infotainment system in a vehicle as well as an instrument cluster with safety requirements and a driver monitoring system can now all run at the same time and independently with hardware separation.

The flexibility needed to support both human and machine vision applications such as production line monitoring and ADAS camera systems.
Enhanced safety features, supports features to achieve ASIL B / SIL2 safety capability.
Support for four real time cameras, or 16 buffered cameras, delivering a 1.2 giga pixel per second throughput.

One for the techie ones on here if has any relevance?
Cambridge, UK, September 29, 2020 – Today, Arm unveiled new computing solutions to accelerate autonomous decision-making with safety capability across automotive and industrial applications. The new suite of IP includes the Arm® Cortex®-A78AE CPU, Arm Mali™-G78AE GPU, and Arm Mali-C71AE ISP, engineered to work together in combination with supporting software, tools and system IP to enable silicon providers and OEMs to design for autonomous workloads. These products will be deployed in a range of applications, from enabling more intelligence and configurability in smart manufacturing to enhancing ADAS and digital ****pit applications in automotive.
“Autonomy has the potential to improve every aspect of our lives, but only if built on a safe and secure computing foundation,” said Chet Babla, vice president, Automotive and IoT Line of Business at Arm. “As autonomous decision-making becomes more pervasive, Arm has designed a unique suite of technology that prioritizes safety while delivering highly scalable, power efficient compute to enable autonomous decision-making across new automotive and industrial opportunities.”
