On a multi- or many-core platform that runs applications of different safety criticality (mixed-criticality), all applications have to be certified to the highest level of criticality, unless they are sufficiently isolated. Isolation enables individual certification of applications and cost-efficient re-certification of single applications after an update. We introduce a parameterizable and synthesizable many-core platform with a fast and scalable monitoring and control mechanism that supports safe sharing of resources. Our contribution is a step towards exploiting the benefits of multi- and many-core platforms for mixed-critical applications.
