Dataflow specifications are suitable to describe both signal processing applications and the relative specialized hardware architectures, fostering the hardware–software development gap closure. They can be exploited for the development of automatic tools aimed at the integration of multiple applications on the same coarse-grained computational substrate. In this paper, the multi-dataflow composer (MDC) tool, a novel automatic platform builder exploiting dataflow specifications for the creation of run-time reconfigurable multi-application systems, is presented and evaluated. In order to prove the effectiveness of the adopted approach, a coprocessor for still image and video processing acceleration has been assembled and implemented on both FPGA and 90 nm ASIC technology. 60 % of savings for both area occupancy and power consumption can be achieved with the MDC generated coprocessor compared to an equivalent non-reconfigurable design, without performance losses. Thanks to the generality of high-level dataflow specification approach, this tool can be successfully applied in different application domains
he Carnic Alps represent the best exposed Paleozoic succession within the Alpine domain being fossiliferous, mostly non-metamorphic and largely complete. This study focuses on the area around Mt. Pizzul, because the bedrocks record well the basin dynamics and most of the units are conodont bearing. Our aims were to contribute to the procedure of formalization of the lithostratigraphic units and to understand the depositional and deformation history of the study area. The area has been mapped, tectonic overprint constrained and the successions described, measured and dated. As a second-order aim, we discuss these data to infer the relations with other parts of the Carnic basin and to recognize the global controls on sedimentation. The depositional evolution can be sketched as follows: pre-Hirnantian ramp-type margin; Hirnantian glacioeustatic-related deposits and unconformity; pelagic deposition in a ramp-type margin (Přídolí–Eifelian); slope formation and differentiation in buildup, foreslope and pelagic environments (Eifelian–Frasnian); transgression and reef drowning (Frasnian–Visean); probable subaerial exposures likely during in uppermost Famennian and Visean times; and turbidite deposition (Visean). Global controls or deposits suggesting a global control are documented, including the Boda Event, the Hirnantian glaciation, the Middle Devonian reef growth, the Kačák Event, and the high-frequency sea-level fluctuations around the Devonian–Carboniferous boundary. The drowning of the buildups here and elsewhere in the Carnic Alps started during the Frasnian, unlike observed globally. This suggests that local tectonics lead to progressive deepening up to the transition to turbidite deposition
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
