IDAMC: A NoC for mixed criticality systems

Abstract

Increasing demand for performance and further integration promotes the use of multi- and many-core systems - also in safety-critical embedded systems. In this domain, hardware platforms obviously have to support real-time, predictability constrained applications such as an anti-lock braking system. However, the on-going trend to integrate multiple functions with different criticalities (mixed critical) on a single platform calls for a paradigm shift. Mixed-critical systems require special attention with respect to functional (access protection) and non-functional (performance) isolation. An additional layer of protection and guaranteed service on the underlying infrastructure enables the efficient adoption of such architectures in safety-critical domains. In this paper, we present the IDAMC, a many-core platform which provides mechanisms to integrate applications of different criticalities on a single platform.
