Last-touch correlated data streaming

Recent research advocates address-correlating predictors to identify cache block addresses for prefetch. Unfortunately, address-correlating predictors require correlation data storage proportional in size to a program's active memory footprint. As a result ...

Deep-submicron embedded processor architectures for high-performance, low-cost and low-power

Sylvain Aguirre

Because the market has an insatiable appetite for new functionality, performance is becoming an increasingly important factor. The telecommunication and network domains are especially touched by this phenomenon but they are not the only ones. For instance, ...

STMBench7: A Benchmark for Software Transactional Memory

Rachid Guerraoui, Michal Kapalka

Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than explicit coarse-grained locking and easier to use than fine-grained locking. However, STM im ...

Reduction of Register File Delay Due to Process Variability in VLIW Embedded Processors

Giovanni De Micheli, David Atienza Alonso, José Luis Ayala Rodrigo

Process variation in future technologies can cause severe performance degradation since different parts of the shared Register File (RF) in VLIW processors may operate at various speeds. In this paper we present a complete approach that handles speed varia ...

Event-Based Programming without Inversion of Control

Martin Odersky, Philipp Haller

The actor computation model is especially suited for concurrent and distributed computations. Actors are basically concurrent processes which communicate through asynchronous message passing. When combined with pattern matching for messages, actor-based pr ...

Understanding the performance of concurrent error detecting superscalar microarchitectures

Babak Falsafi

Superscalar out-of-order microarchitectures can be modified to support redundant execution of a program as two concurrent threads for soft-error detection. However, the extra workload from redundant execution incurs a performance penalty due to increased c ...

ReCast: Boosting tag line buffer coverage in low-power high-level caches "for free"

Babak Falsafi

We revisit the idea of using small line buffers in-front of caches. We propose ReCast, a tiny tag set cache that filters a significant number of tag probes to the L2 tag array thus reducing power. The key contribution in ReCast is S-Shift, a simple indexin ...

Processor Enhancements for Media Streaming Applications

Pierre Vandergheynst, Sébastien Bilavarn

The development of more processing demanding applications on the Internet (video broadcasting) on one hand and the popularity of recent devices at the user level (digital cameras, wireless videophones, ...) on the other hand introduce challenges at several ...

Fault-tolerant parallel applications with dynamic parallel schedules

Roger Hersch, Sebastian Gerlach

Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore drive the MTBF of such clusters to unacceptable levels. The software framewo ...
