Recent work in the FPGA acceleration of molecular dynamics simulation has shown that including on-the-fly neighbor list calculation (particle filtering) in the device has the potential for an 80× per core speed-up over the CPU-based reference code and so to make the approach competitive with other computing technologies. In this paper we report on progress and challenges in advancing this work towards...
This paper introduces the design of an automobile driving simulation system based on single chip computer. It's control device, with 8 bit single chip computer STC89LE516AD as its core, assisted by data acquisition circuit, data storage circuit, and data communication circuit, performs the function of collection, storage and communication of the driving information. Furthermore, with the help of visual...
The capacity problem is one of the main issues in researching the multi-channel IEEE 802.11 wireless networks. In this paper, we analyze the path capacity of the multi-channel wireless networks by estimating the RTS, CTS and the packet loss rate of the wireless links and calculating the average service time of the packet sending. We also analyze the channel assignment and channel switching problems...
In this paper, we present a Maude-based tool for embedded systems specification, performance estimation and formal verification of some properties. In our case, the application is modeled as a network of concurrent tasks with coarse grained actions (CGAs) that communicate with each other via abstract channels following Kahn process networks (KPNs) model of computation semantics. In order to achieve...
This paper presents a novel model for average current control that can be applied to the buck-cascaded buck-boost converter (BuCBB) with two independently controlled switches in universal input power factor correction (PFC) circuits. The proposed BuCBB PFC model consists an averaged BuCBB topology with all the switching elements replaced by dependent sources and an average current control scheme with...
This paper presents the module of pulse power circuit based on RSD in SABER-Simulink co-simulation environment (SSCSE). In SSCSE, physical model of RSD is built in Simulink, pulse power circuit based on RSD model and magnetic switch model are built in SABER, and simulation data is exchanged through SABER Cosim interface. Compute formula of magnetic switch saturation time is derived. Single pulse and...
Large-scale mobile radio systems using dynamic channel REassignment switch the channels assigned to some of the calls in progress to maintain a nearly optimum separation between coverage areas simultaneously using the same channel. Dynamic channel REassignment produces a significant increase in channel occupancy. For example, in the systems studied, which have a uniform distribution of their fixed...
