Xilinx Ultrascale+ Safety Platform

Example for an Ultrascale+ Safety Platform

This solution shall meet the following requirements:

Linux on Cortex-A53 Quad-Core

We want to use a symmetric multiprocessing with Linux on the Cortex-A53 Quad-Core for high performance calculations.

Flexible Safety RTOS on Cortex-R5

To meet safety diagnostic coverage, we run Cortex-R5 in Lock-Step Mode with the Flexible Safety RTOS.

Safe Inter-Core Communication

We want to use an end-to-end protected communication between the Linux and RTOS application parts.

Furthermore, this solution shall meet some high-level business goals:

Integrated Platform

We want to start application development, without the need of integration activities of RTOS and Linux system

LTS for complete Platform

We want to have a long-term supported (LTS) safety platform.

Description

This usage scenario provides a Linux application software on a high performance quad-core Cortex-A53, monitored by the Flexible Safety RTOS running on the lockstep Cortex-R5 cores. A safe communication and monitoring library completes this high performance system. All safety software parts are already pre-certified.
