In this paper, we propose an asynchronous wrapper with novel handshake circuits for data communication to be used in GALS systems. The handshake circuits include two communication ports and a local clock controller. We present two approaches for the implementation of communication ports; one with pure standard cells and the other with Müller C elements.The… (More)
In this paper we discuss some aspects of designing low power asynchronous wrappers for use in GALS based communication systems. We propose a general method for designing asynchronous wrappers for use in asynchronous multiport-to-multiport communication channels with low swing busses and variable power supply voltages.
An FPGA-Based servo controller for permanent magnet synchronous motor (PMSM) drive is designed and realized in this paper. The FPGA-Based controller has two modules. One module performs the function of the current/speed loop control for PMSM drives, which includes vector control strategy, the PI regulator, coordinate transformation, the SVPWM generator. The… (More)
This paper derives the channel filters' symmetry polarities (symmetric or anti-symmetric impulse responses), length parities (even or odd), and permissible combinations and lengths of M-channel linear-phase perfect reconstruction (PR) maximally decimated filter banks. The results are general and can be used for any number of channels M.
In this paper, we propose a VLSI implementation method for one-dimensional discrete wavelet transform (1D-DWT) based on the GALS systems approach. An asynchronous wrapper, which includes two data communication ports and a local clock controller, is designed for the asynchronous data communication between the locally synchronous filtering modules in the… (More)
In this paper, we propose an asynchronous wrapper with new handshake circuits for the data communication in GALS systems. The handshake circuits include two data-ports and a local clock controller. we present two approaches for the implementation of dataports; one with pure standard cells and the other with Muller-C elements.The detailed design methodology… (More)
The GALS (Globally Asynchronous Locally Synchronous) approach is highly suitable for implementation of communication systems. In this paper we describe an efficient design flow for GALS design based on commercial tools. As design example we have selected a digital FIR filter. It is a nontrivial task to develop an efficient design flow for GALS based systems… (More)
In this paper, we present an efficient design flow for GALS systems based on the state-of-art commercial tools, we first designed an asynchronous wrapper equipped with handshake circuits and stoppable clock generator, and then selected a digital FIR filter as a design example. The simulation and verification show our proposed interface circuits is of good… (More)
This paper focuses on synchronization of fractionalorder complex dynamical networks with decentralized adaptive coupling. Based on local information among neighboring nodes, two fractional-order decentralized adaptive strategies are designed to tune all or only a small fraction of the coupling gains respectively. By constructing quadratic Lyapunov functions… (More)
