Master's thesis - Software and Hardware Architecture for Redundant Embedded Systems

Superproject containing projects I worked on and pdf document that is my master's thesis.

Abstract

Investigate the redundant architectures for embedded systems with respect to possibilities of redundancy implementation in hardware and software. Compare Cortex-R and Cortex-M microcontroller architectures with respect to redundancy in systems with functional safety requirements. Implement software for redundancy on the selected processor architecture. The software must include a bootloader and a modified FreeRTOS operating system. The bootloader must support the ability to load new applications and contain a command shell with accompanying functions. The modified FreeRTOS operating system must provide features of tracking the individual tasks execution time and task replication.
