Towards Temporal and Spatial Isolation in Memory Hierarchies for Mixed-Criticality Systems with Hypervisors
In mixed-criticality systems, applications with different levels of criticality are integrated on the same computational platform. Without a proper isolation of the different applications of such a mixed-criticality system certification gets expensive, because it has to be shown that application components of lower criticality do not hamper the correct operation of the critical applications. Th...
متن کاملPredictable transactional memory architecture for hierarchical mixed-criticality systems
A transactional memory simplifies the concurrency management in multicore systems by permitting sets of load and store instructions to be executed in an atomic way. The correct results for concurrent transactions and the execution time strongly depend on the coherency potentials, rollback capabilities and strategies of the transactional memory. A transactional memory can be implemented as a Har...
متن کاملFormal Analysis of Predictable Data Flow in Fault-Tolerant Multicore Systems
The need to integrate large and complex functions into today’s vehicle electronic control systems requires high performance computing platforms, while at the same time the manufacturers try to reduce cost, power consumption and ensure safety. Traditionally, safety isolation and fault containment of software tasks have been achieved by either physically or temporally segregating them. This appro...
متن کاملNovel Hybrid Scheduling Technique for Sensor Nodes with Mixed Criticality Tasks
Sensor networks become increasingly a key technology for complex control applications. Their potential use in safety- and time-critical domains has raised the need for task scheduling mechanisms specially adapted to sensor node specific requirements, often materialized in predictable jitter-less execution of tasks characterized by different criticality levels. This paper offers an efficient sch...
متن کاملWord processors with line wrap: Cascading, self-organized criticality, random walks, diffusion, and predictability.
We examine the line-wrap feature of text processors. We show that adding characters to previously formatted lines leads to the cascading of words to subsequent lines. The length of these cascades shows a power-law distribution. We show that this system is in a state of self-organized criticality. The connection to onedimensional random walks and diffusion problems is demonstrated. Of particular...
