In multi-core systems, main memory is a major shared resource among processor cores. A task running on one core can be delayed by other tasks running simultaneously on other cores due to interference in the shared main memory system. Such memory interference delay can be large and highly variable, thereby posing a significant challenge for the design of predictable real-time systems. In this paper, we present techniques to reduce this interference and provide an upper bound on the worst-case interference on a multi-core platform that uses a commercial-off-the-shelf COTS DRAM system.

We explicitly model the major resources in the DRAM system, including banks, buses, and the memory controller. By considering their timing characteristics, we analyze the worst-case memory interference delay imposed on a task by other tasks running in parallel.

We find that memory interference can be significantly reduced by i partitioning DRAM banks, and ii co-locating memory-intensive tasks on the same processing core. Based on these observations, we develop a memory interference-aware task allocation algorithm for reducing memory interference. Experimental results show that the predictions made by our approach are close to the measured worst-case interference under workloads with both high and low memory contention.

The physical structure of priority queues, bank schedulers, and the channel scheduler depends on the implementation. This assumption is required to bound the re-ordering effect of the memory controller, which will be described in Sect. Note that the write-buffer draining does not completely block read requests until all the write requests are serviced.

Hence, even when the write buffer is being drained, a read request can be scheduled if its commands are ready with respect to DRAM timing constraints e. McCalpin JD. Software cache partitioning simultaneously partitions the entire physical memory space into the number of cache partitions.

In: IEEE international conference on trust, security and privacy in computing and communications, Int J Embed Syst 2 3 —The conference is a forum for active discussions on various topics of current and future importance to designers and researchers. The program of the conference brings together the latest and the best in academic and industrial research and development.

High-quality original papers will be accepted for oral presentation followed by interactive poster sessions. The conference covers a wide range of design issues and applications relevant to important embedded system quality metrics including performance, cost, power consumption, reliability, security, and usability.

The following relevant areas are representative but not exhaustive. Track 2 Domain and application-specific design techniques - Analysis, design, and optimization techniques for multimedia, medical, automotive, security, and other specialized application domains, cyber-physical systems.

Track 3 Embedded software - Compilers, memory management, virtual machines, scheduling, operating systems, realtime support, fault-tolerance, and middleware. Track 4 Embedded systems architecture - Architecture and micro-architecture design, exploration and optimization including application-specific, storage systems, memory and communication, networks-on-chip. Track 7 Power-aware systems - Power- and energy-aware system design and methodologies ranging from low-power embedded systems to energy-efficient large scale systems such as Green IT and Smart Grid.

Submission Information Papers must represent original work, not published or submitted for publication in other forums. A blind review process will be enforced. Authors must not reveal their identity directly or indirectly. For formatting instructions and templates, visit the ACM web site. Of note, 10 pages is an upper limit.
