ISOLDE Customizable Instruction Sets and Open Leveraged Designs of Embedded riscv processors


The KDT-JU programme aims to support the digital transformation of all economic and societal sectors, and speed up the transition towards a green, climate neutral and digital Europe. This transformation includes the development of new semiconductor components, such as processors, as these are considered of key importance in retaining technological and digital sovereignty and build on significant prior EC investment in knowledge generation in this domain.


ISOLDE is a KDT-JU-funded project with a duration of three years starting on May 1st 2023. The goal of ISOLDE project is to create, expand, and industrialize a European high-performance RISC-V open-source ecosystem to reduce dependence on non-EU technology suppliers and to strengthen competitive domestic microelectronics production. The targeted application area of ISOLDE is embedded systems that require significant computing power due to future functional requirements, while still being able to be part of safety-critical systems. Therefore, support for safety and security technologies is also part of the objective.


In this context, OFFIS cooperates with 38 other European partners and contributes to the safety and security part of the ISOLDE project, known as Safety Island. OFFIS develops an open-source, generic, and configurable contract-based timing monitoring co-processor. This co-processor monitors the safety/security related system behaviours at runtime, collected by the infrastructure of the Safety Island, to guarantee the correct execution of these behaviours. Furthermore, OFFIS provides a compiler for initialization of the co-processor and configuration of the monitoring specifications. Finally, the results will be integrated with the other partners‘ components and presented in an automotive demonstrator.
