    Application-Specific Express Virtual Channels Insertion for Low-Power NoCs

    A flow control mechanism, express virtual channels (EVCs), was recently presented to close the gap between packet-switched networks and the ideal interconnection through virtually bypass intermediate routers. Currently, EVCs paths are inserted regularly. This paper proposes a novel methodology to insert EVCs in an application-specific way (AS-EVC) by exploiting communication characteristics of applications, with the main objective to reduce more NoCs power. Additionally, accurate evaluations were performed based on low-level, synthesizable models. The results on a range of synthetic and real workloads show that up to 23.49% router power is saved by AS-EVC, compared to the baseline design. Also, AS-EVC outperforms static EVCs under all traffics, with 57.14% more power is saved on average for tested Minne-SPEC benchmarks.APSIPA ASC 2009: Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference. 4-7 October 2009.

(Morretes). Por estudos de metilação, foi verificado que o polímero é ramificado e contém 29,0% de resíduos ramificados (pontos de- ramificação nos carbonos C3 e C6 de resíduos de D-galactose) e 29,5% de resíduos terminais não redutores (28,0% de resíduos de D-galactose e 1,5% de resíduos de fucose). O polímero apresenta uma alta proporção de cadeias lineares formadas de resíduos de D-galactose interligados pelos seguintes tipos de ligações glicosídicas: 26,0% do tipo (1-6), 11,0% do tipo (1-2) e 4,5% do tipo (1-3)
