This article proposes a concept of dynamic profiling reconfigurable instruction set processor (RISP) and related retargetable tool chain support. The tool chain consists of a profiler, a code map per, and a retargetable compiler. Firstly dynamic profiler is employed to obtain hot path for applications. Then hot block is implemented in reconfiguration logic units. After newly designed hardware block...
Profiling plays an important role in performance optimization, such as instruction set optimization, dynamic binary translation and so on. Unfortunately, profilers nowadays often lack in efficiency on two key attributes: accuracy and profiling time. In this paper, we introduce a configurable hardware path profiler deriving from previous work, based on the idea of sampling and path profiling. The profiler...
This paper suggests a novel method named WTGRNN, which is based on generalized regression neural network (GRNN) with wavelet transform (WT) as a pre-processing tool for the simultaneous spectrophotometric determination of o-nitro-aniline, m-nitro-aniline and p-nitro-aniline. Wavelet representations of signals provide a local time-frequency description, thus in the wavelet domain, the quality of noise...
This paper focuses on the problem of robust fault-tolerant control for uncertain linear discrete systems with time-delay. On the basis of Lyapunov theory, it is found that a controller based on a kind of memory feed-back control law can keep the uncertainty systempsilas integrity against the actuator failures, and make use of the LMI toolbox in Matlab, we can get the parameters of the controller....
Combined neural networks, sliding model variable structure control with robust Hinfin control theory, the control problems of complex systems were studied. A new control strategy is proposed for a class of nonlinear time-delay systems. By adding a neural networks sliding model compensate controller, this scheme can guarantee the systems, which have uncertain terms and disturbance, to be stable. Made...
There is a large area of saline-alkali soil in Chinese coastland, especially in Tianjin and Cangzhou. The steel grounding bodies of the power plants, substations, transmission lines and distribution equipment in such area are corroded seriously by saline-alkali soil. For example, in some 220kV substations in Tianjin area, the steel grounding grids have been corroded by 60% after operating for only...
