Performance Prediction on Multi-core Processors
2010 International Conference on Computational Intelligence and Communication Networks, 2010Contention for shared resources between co-running programs on a multi-core processor causes degradation of performance. Previous research work made efforts to characterize and classify memory behavior of programs to predict their performance. Such knowledge may be used to design workloads for performance studies on multi-core processors. It could also

A Reconfigurable Audio Beamforming Multi-Core Processor
2011Over the last years, the Beamforming technique has been adopted by the audio engineering society to amplify the signal of an acoustic source, while attenuating any ambient noise. Existing software implementations provide a flexible customizing environment, however they introduce performance limitations and excessive power consumption overheads.

Parallel Real-Time OLAP on Multi-core Processors
2012 12th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (ccgrid 2012), 2012One of the most powerful and prominent technologies for knowledge discovery in decision support systems is online analytical processing (OLAP). Most of the traditional OLAP research, and most of the commercial systems, follow the static data cube approach proposed by Gray et.al.

A freespace crossbar for multi-core processors
Proceedings of the 22nd annual international conference on Supercomputing, 2008A new package-level interconnect is described that adapts carbon nanoemissive display technology to create an inexpensive package-level freespace crossbar with single-cycle source-to-target latency. Interconnections are made using filamentary electron beams as the data transmission medium.

Communication Control for Multi-core Processors
2012 Third International Conference on Digital Manufacturing & Automation, 2012A reconfigurable System-on-Chip (SoC) for multimedia application was introduced in this paper, where the SoC consisted of a master processor and slave processor. We individually simulated the master processor with DLX pipeline processor and the slave processor with Xtensa processor that was able to establish a excellent multimedia processor with multi ...

Standard Multi-Core Processors
2011For a long time, the performance of general-purpose processors could be improved by increasing clock frequency and instruction level parallelism (ILP). Nowadays, only diminished gains in performance can be reached by higher processor clock rates. This results from the difficulty to find enough parallelism in the instruction stream of a single process ...

Thermal Modeling of Multi-Core Processors
Thermal and Thermomechanical Proceedings 10th Intersociety Conference on Phenomena in Electronics Systems, 2006. ITHERM 2006., 2006A thermal model was developed to investigate the effect of multi-core microprocessor circuit layout on thermal performance. Die size of 20 mm times 20 mm and power dissipation of 200W were assumed in the model. A high thermal conductivity heat spreader of 50mm times 50 mm times 2 mm and air-cooled heat sink base of 100 mm times 100 mm times 5 mm were ...

Meeting Real-Time Requirements with Multi-core Processors
2012Many multi-core processors exhibit characteristics that make it difficult or even impossible to use them in safety-critical real-time systems. To prevent sporadic failures and late-stage integration problems, the hardware properties of the processor and its peripherals have to be checked for their real-time capability at an early project stage ...
