I can see this intensifying competition in microcontrollers where there's a split between many ARM licensees and the Microchips and Renesas-es.

Real time was a last bastion for some of these guys

This looks to be a path breaking architecture .

I am just curious to know whether this will this bring more standardization in the automotive software development process and may it more individualistic.

For security certification it may be advisable to have some kind of standardization in the software modules and their integration process.

With driver-less cars now on the horizon this is all the more important an issue

Frankly, I see this announcement of ARM just as a marketing blob. They want to ride the A7 wave.

Let me reason why:

- Todays Cortex-R4 offers already the protection mechanisms needed to run safety and non safety software on the same chip (see TI's TMS570, RM4x).

- No one needs 64bit unless he wants to run Android for the multimedia stuff inside a deeply embedded device.

- The "protection" needed is more a bus thing then a CPU thing which is already implemented in ARM devices or PowerPC devices (see FSL Quoriva).

- Do we really want the breaking system software run on our radio? (Ok, this is not an rational argument)


So what is now the reason for this "new" architecure?

Yes indeed. I imagine NVIDIA and other chip companies are hot to  get into the lucrative automotive space, and ARM is giving the the foot-in-the-door they need. The competition should bring many benefits to the consumer--new features, capabilities and options.

Although ARM's announcement today came with no names for potential licensees for the new v8-R architecture, Nvidia's comments in the story make it clear that the hardware-supported virtualization feature, enabled in the new architecture,  is something very much in demand by chip companies hot to trot for developing automotive platform.

Exactly. I agree, Colin. As I understand it, this has been a big headache for them.

Similarly, this should make it easier for SoC design, according to the Linley Group's Kevin Krewell.

The new ARMv8-R virtualization with its "bare-metal" hypervisor mode should prove to be really popular among software developers wanting to add-on functionality while maintianing all the safety that automotive demands.
