Interactive Exploration of Cosmological Dark-Matter Simulation Data

3 weeks ago
The winning entry of the 2015 IEEE Scientific Visualization Contest, this article describes a visualization tool for cosmological data resulting from dark-matter simulations. This video demonstrates the tool’s individual elements as well as the overall application the authors created by combining them.

Linear Branch Entropy: Characterizing and Optimizing Branch Behavior…0317 Spanish

3 weeks ago
In this paper, we propose linear branch entropy, a new metric for characterizing branch behavior. Linear branch entropy is independent of the configuration of a specific branch predictor, but is highly correlated with the branch misprediction rate of any predictor. In particular, we empirically derive a linear relationship between linear branch entropy and branch misprediction […]

“Local Culture, Global Habit”

PEAF: A Power-Efficient Architecture for SRAM-Based FPGAs Using Reconfigurable Hard Logic Design…

1 month ago
Significant increase of static power in nano-CMOS era and, subsequently, the end of Dennard scaling has put a Power Wall to further integration of CMOS technology in Field-Programmable Gate Arrays (FPGAs). An efficient solution to cope with this obstacle is power gating inactive fractions of a single die, resulting in Dark Silicon. Previous studies employing […]

Aging Resilience and Fault Tolerance in Runtime Reconfigurable Architectures

1 month ago
Terms—Runtime reconfiguration, aging mitigation, fault-tolerance, resilience, graceful degradation, FPGARuntime reconfigurable architectures based on Field-Programmable Gate Arrays (FPGAs) allow area- and power-efficient acceleration of complex applications. However, being manufactured in latest semiconductor process technologies, FPGAs are increasingly prone to aging effects, which reduce the reliability and lifetime of such systems. Aging mitigation and fault tolerance techniques […]

Design and Applications for Embedded Networks-on-Chip on FPGAs

1 month ago
Field-programmable gate-arrays (FPGAs) have evolved to include embedded memory, high-speed I/O interfaces and processors, making them both more efficient and easier-to-use for compute acceleration and networking applications. However, implementing on-chip communication is still a designer’s burden wherein custom system-level buses are implemented using the fine-grained FPGA logic and interconnect fabric. Instead, we propose augmenting FPGAs […]

Always-On Speech Recognition Using TrueNorth, a Reconfigurable, Neurosynaptic Processor

1 month ago
Deep neural networks (DNN) have been shown to be very effective at solving challenging problems in several areas of computing, including vision, speech, and natural language processing. However, traditional platforms for implementing these DNNs are often very power hungry, which has lead to significant efforts in the development of configurable platforms capable of implementing these […]

Deadlock Verification of Cache Coherence Protocols and Communication Fabrics 0217 Chinese

1 month ago
Cache coherence plays a major role in manycore systems. The verification of deadlocks is a challenge in particular, because deadlock freedom is an emerging property. Formal methods often decouple verification of the protocol from verification of the communication interconnect. Modern communication fabrics, however, become more advanced and include a network topology, routing, arbitration, synchronization, and […]
