The performance of an FPGA based CNN accelerator is determined by both parallelism and frequency, however, most prior works optimize the parallelism in the RTL design and resolve the frequency after the synthesis. This paper presents a design space exploration method for the pipeline implementation of the deep CNN models, which concurrently optimizes parallelism and frequency to achieve a comprehensive...
The study is mainly about the simulation of the hydrodynamic effect of the fluid around the semi-submerged body in the three-dimensional open channel flow. In the case of Reynolds number 36200 and Froude number 0.17, the simulation is carried out by unsteady Reynolds Average Navier-Stokes method for semi-submerged body. There are four different draft ratios simulation by volume of fluid. The researches...
Physical Unclonable Function (PUF) is a new hardware security primitive that exploits the manufacturing variations of integrated circuits. Traditional arbiter PUF is vulnerable to machine learning based modeling attacks due to its linearity. Current mirror PUF uses non-linear current mirror to bring non-linearity into the challenge-response relationship and is claimed resistant to modeling attacks...
Compared with the observable behavior, it is difficult to predict the hidden behavior of a complex system. In the existing methods for predicting the hidden behavior, a lot of testing data (usually quantitative information) are needed to be sampled. However, some complex engineering systems have the following characteristics: 1) The systems cannot be tested periodically, and the observable information...
In recent years, water pollution incidents happen frequently, causing serious disasters and society impact. It is advocated that water quality monitoring sensors shall be deployed in water distribution systems to realize the real-time pollution detection such that we can effectively detect the water pollution event to reduce the risk. However, how to deploy water quality sensors in water distribution...
It is a difficult problem to build the aeroengine model. And it is hard to meet aeroengine control demand by traditional methods. So according these problems, aeroengine models were built including “little deflection” model and “large deflection” models. A fuzzy controller was designed which had the parts of parameter adjustment control and smith forecast and compensation control. The simulation of...
Differential signaling is widely used in high speed data communications. Inter-symbol interference (ISI) and crosstalk between differential pair, however, heavily affect the integrity of differential signaling as measured by timing jitter and amplitude noise in the eye diagram. To reduce the impact of ISI, a pre-emphasis filter is commonly used, but it increases the crosstalk noise. In this paper,...
