Multi-core application development with Zephyr RTOS

"Performance in Desktop, Server, HPC and even smartphone applications has been scaling rapidly in recent years via multi-core, continuously increasing the number of cores on a processor chip. The same principle has been extending to embedded systems, where multi-core designs are increasingly more pervasive in applications such as 5G data processor, edge IoT, Machine Learning and many more.
This presentation will examine multicore application options and considerations using the Zephyr. We'll start from exploration of use-cases where multiple CPU cores might be beneficial for deeply embedded system including both asymmetric & symmetric multiprocessing (AMP & SMP). Then we'll discuss current state of multi-core support in Zephyr: what is already implemented and what's still missing. And in the end we will highlight challenges associated with designing high performance software applications for multi-core hardware using samples on boards currently supported in upstream Zephyr project."

Alexey Brodkin is an engineering manager at Synopsys. He's been working with embedded systems for years starting from 8-bit MCUs gradually shifting to high-performance multi-core 32-bit CPUs, in fact Alexey is ARC architecture custodian at U-Boot bootloader, co-maintainer of Linux kernel port for ARC as well as casual contributor to some other open source projects he uses in his professional affairs.
And today with raised complexity of deeply embedded systems which warrants more complicated software to be used, Alexey tries to apply his knowledge and experience with full-scale multi-core CPUs to the Zephyr RTOS.
