Atualização do processador e módulo de tolerância à falhas no projeto CEVERO

Abstract

For critical applications such as aerospace, systems must have great robustness to face the hostile environment of space. Therefore, it is necessary to implement fault tolerance strategies to ensure its operation. To supply this demand CEVERO project by UFRN proposed in 2019 a fault-tolerant processor using hardware redundancy. Due to changes and loss of support on its base technologies, the CEVERO core became outdated and blocked to progress with the development. This work will present a new architecture for the CEVERO core, changing the old processor known as zero-riscy for its continuation, IBEX: a RISC-V processor maintained and developed by lowRISC. With this update, new possibilities emerges for the progress of CEVERO, as well as cooperation with other projects.
