Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (Association for Computing Machinery (ACM), 2009)
Text en actes de congrés
Accés restringit per política de l'editorialNon-Uniform Cache Architectures (NUCA) have been proposed as a solution to overcome wire delays that will dominate on-chip latencies in Chip Multiprocessor designs in the near future. This novel means of organization divides ... -
Case for a field-programmable gate array multicore hybrid machine for an image-processing application
Rakvic, R.; Ives, Robert W.; Lira Rueda, Javier; Molina Clemente, Carlos (2011-01)
Article
Accés restringit per política de l'editorialGeneral purpose computer designers have recently begun adding cores to their processors in order to increase performance. For example, Intel has adopted a homogeneous quad-core processor as a base for general purpose ... -
Compiler analysis for trace-level speculative multithreaded architectures
Molina Clemente, Carlos; González Colás, Antonio María; Tubella Murgadas, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2005)
Text en actes de congrés
Accés obertTrace-level speculative multithreaded processors exploit trace-level speculation by means of two threads working cooperatively. One thread, called the speculative thread, executes instructions ahead of the other by speculating ... -
Implementing a hybrid SRAM / eDRAM NUCA architecture
Lira Rueda, Javier; Molina Clemente, Carlos; Brooks, David; González Colás, Antonio María (2010-08-27)
Report de recerca
Accés obertIn this paper, we propose a hybrid cache architecture that exploits the main features of both memory technologies, speed of SRAM and high density of eDRAM. We demonstrate, that due to the high locality found in emerging ... -
Improving the prefetching performance through code region profiling
Torrents Lapuerta, Martí; Martínez, Raul; Molina Clemente, Carlos (Barcelona Supercomputing Center, 2015-05-05)
Text en actes de congrés
Accés obertIn this work, we propose a new technique to improve the performance of hardware data prefetching. This technique is based on detecting periods of time and regions of code where the prefetcher is not working properly, ... -
Last Bank: dealing with address reuse in non-uniform cache architecture for CMPs
Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (2009-01-16)
Report de recerca
Accés obertIn response to the constant increase in wire delays, Non-Uniform Cache Architecture (NUCA) has been introduced as an effective memory model for dealing with growing memory latencies. This architecture divides a large memory ... -
LRU-PEA: A smart replacement policy for non-uniform cache architectures on chip multiprocessors
Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (2009-05-14)
Report de recerca
Accés obertThe increasing speed-gap between processor and memory and the limited memory bandwidth make last-level cache performance crucial for CMP architectures. Non Uniform Cache Architectures (NUCA) has been introduced to deal ... -
