Arm is known for its Cortex range of processors in mobile devices, however the mainstream Cortex-A series of CPUs which are used as the primary processing units of devices aren’t the only CPUs which the company offers. Alongside the microcontroller-grade Cortex-M CPU portfolio, Arm also offers the Cortex-R range of “real-time” processors which are used in high-performance real-time applications. The last time we talked about a Cortex-R product was the R8 release back in 2016. Back then, the company proposed the R8 to be extensively used in 5G connectivity solutions inside of modem subsystems.
Another large market for the R-series is storage solutions, with the Cortex-R processors being used in HDD and SSD controllers as the main processing elements.
Today, Arm is expanding its R-series portfolio by introducing the new Cortex-R82, representing the company’s first 64-bit Armv8-R architecture processor IP, meaning it’s the first 64-bit real-time processor from the company.
AnandTech and its usual deep dive into the intricacies of this new lineup from ARM. Obviously these kinds of chips are not something most people actively work with – we tend to merely use them, often even without realising it.
Marketing drivel. Real-time is property of the OS not the hardware. So mean the first 64-bit micro controller? Though I seriously doubt that as well.
