ARM's new Cortex R-52 replaces the aging R-5 and they report that it will run 14 times faster than the model it replaces. It is also the first ARMv8-R based product they have released, it supports hypervisor instructions as well as additional unspecified safety features. They are aiming for medical applications as well as vehicles, markets which are currently plagued by insecure software and hardware. In many cases the insecurity stems from companies using the default software settings in their products, often due to ignorance as opposed to malice and ARM intends their default settings to be far more secure than current SOCs. Unfortunately this will not help with those who use default passwords and ports but it is a step in the right direction. Pop over to The Inquirer for more information.
"The Cortex R-52 has been five years in development and is engineered to meet new safety standards as ARM takes aim at the growing market of large-scale smart devices, such as surgical robots and self-driving cars."

“they report that it will run
“they report that it will run 14 times faster than the model it replaces.”
I’m reading 14 times faster context switching… not simply 14 times faster.
14 times faster context switching only makes context switching 14 times faster, not the processing.
So the “up to” 4 cores in
So the “up to” 4 cores in lock step is for redundancy(?) like the rockets have but for cars to make sure there are no mistakes to make the car go up onto the sidewalk and hit some folks. ARM Holdings needs to give us some white-papers/data sheets links and put the links in the graphics, because those “Technology” reporters are not going to do a good job at explaining things.
Well Tesla motors has Jim Keller, and I’ll bet that the car computer/s will run the ARMv8A ISA. This SKU is probably not for the main car navigation in the first place. It’s probably for the many sensing related components that report their readings back to the main redundant SOC’s(in separate locations with redundant wiring/power systems) with the processing capability CPU/GPU to make the actual decisions for any multi-ton vehicle tooling down the highway at high speed. Tesla needs that Jim Keller designed system yesterday, but it’s not something to be taken lightly least some may loose their heads like some famous Hollywood starlet way back in the day. Cars operate for many billions of more hours than the average space rocket! So those car navigation systems have to be even more robust or the lawyers will begin to circle with their sharp pearly whites in full view!
The CPU performance is not
The CPU performance is not going to be fast, considering that “In order execution” part. Even with up to 4 cores, ARM’s multi-core performance scaling is usually bad.
