Implementing Mixed Criticality Systems in Ada
2011Many safety-critical embedded systems are subject to certification requirements. However, only a subset of the functionality of the system may be safety-critical and hence subject to certification; the rest of the functionality is non safety-critical and does not need to be certified, or is certified to a lower level.

Smart Certification of Mixed Criticality Systems
2005High integrity applications, such as those performing safety or security critical functions, are usually built to conform to standards such RTCA DO-178B [1] or UK Def Stan 00-55 [2]. Typically such standards define ascending levels of criticality each of which requires a different and increasingly onerous level of verification.

Towards the Design of Certifiable Mixed-criticality Systems
2010 16th IEEE Real-Time and Embedded Technology and Applications Symposium, 2010Many safety-critical embedded systems are subject to certification requirements; some systems may be required to meet multiple sets of certification requirements, from different certification authorities. Certification requirements in such "mixed-criticality" systems give rise to some interesting scheduling problems, that cannot be satisfactorily ...

Mixed-Criticality Systems as a Service for Non-critical Tasks
2016 IEEE 19th International Symposium on Real-Time Distributed Computing (ISORC), 2016Mixed-Criticality Systems are capable of accommodatingtasks of varying criticality. In this paper, these are [life, mission, and non-critical]. Tasks usually have an overestimatedexecution time to allow for the Worst Case Execution Time(WCET). When these tasks finish execution prior to their allottedexecution time due to pessimistic assumptions present

Embedded systems for safety-critical and mixed-criticality applications
2013 2nd Mediterranean Conference on Embedded Computing (MECO), 2013Summary form only given. Multi-core processors promise a number of benefits for development of dependable embedded systems. They offer higher performance than single-core processors and consume less energy than high-speed single cores of equivalent computational power, reducing this way a number of computational nodes and wiring in a system and ...

Scheduling Mixed-Criticality Real-Time Systems
2013This dissertation addresses the following question to the design of scheduling policies and resource allocation mechanisms in contemporary embedded systems that are implemented on integrated computing platforms: in a multitasking system where it is hard to estimate a task's worst-case execution time, how do we assign task priorities so that 1) the ...

Composable Virtual Platforms for Mixed-Criticality Embedded Systems
2014Recent trends show a steady increase towards concurrently executing more and more applications on a single embedded system. Multi-Processor System-on-Chip (MPSoC) architectures are proposed to allow complex design of embedded systems. This is achieved by integrating as many processing resources as possible on a single chip and therefore enabling the ...
