A hardware evaluation of cache partitioning to improve utilization and energy-efficiency while preserving responsiveness
(ACM, 2013)
Text en actes de congrés
Accés obertComputing workloads often contain a mix of interactive, latency-sensitive foreground applications and recurring background computations. To guarantee responsiveness, interactive and batch applications are often run on ... -
A two level load/store queue based on execution locality
(Institute of Electrical and Electronics Engineers (IEEE), 2008)
Text en actes de congrés
Accés obertMulticore processors have emerged as a powerful platform on which to efficiently exploit thread-level parallelism (TLP). However, due to Amdahl’s Law, such designs will be increasingly limited by the remaining sequential ... -
Access to vectors in multi-module memories
(Institute of Electrical and Electronics Engineers (IEEE), 1994)
Text en actes de congrés
Accés obertThe poor bandwidth obtained from memory when conflicts arise in the modules or in the interconnection network degrades the performance of computers. Address transformation schemes, such as interleaving, skewing and linear ... -
ADAM : an efficient data management mechanism for hybrid high and ultra-low voltage operation caches
(2012)
Text en actes de congrés
Accés restringit per política de l'editorialSemiconductor technology evolution enables the design of ultra-low-cost chips (e.g., below 1 USD) required for new market segments such as environment, urban life and body monitoring, etc. Recently, hybrid-operation (high ... -
Adapting cache partitioning algorithms to pseudo-LRU replacement policies
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Text en actes de congrés
Accés obertRecent studies have shown that cache partitioning is an efficient technique to improve throughput, fairness and Quality of Service (QoS) in CMP processors. The cache partitioning algorithms proposed so far assume Least ... -
Adaptive runtime-assisted block prefetching on chip-multiprocessors
(2016-04-29)
Article
Accés obertMemory stalls are a significant source of performance degradation in modern processors. Data prefetching is a widely adopted and well studied technique used to alleviate this problem. Prefetching can be performed by the ... -
An adaptive controller to save dynamic energy in LP-NUCA
(Universidad de La Laguna. Servicio de Publicaciones, 2011)
Text en actes de congrés
Accés obertPortable devices often demand powerful processors to run computing intensive applications, such as video playing or gaming, and ultra low en-ergy consumption to extend device uptime. Such con-flicting requirements are hard ... -
