A Design Path for Design of GALS Based Communication Systems
نویسندگان
چکیده
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 because of the asynchronous parts. Both simulation and implementation tools typically have problems handling the asynchronous part of the GALS system. We have therefore developed a set of asynchronous interface circuits to increase the design efficiency by allowing standard design tools to better support GALS based designs.

An Efficient LUT Design on FPGA for Memory-Based Multiplication
An efficient Lookup Table (LUT) design for memory-based multiplier is proposed. This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...
متن کاملDesign and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
متن کاملContributions to Asynchronous Communication Ports for GALS Systems
Digital systems commonly use a single global clock signal to synchronize the whole system. This is not always possible and it can be more advantageously to divide the system into separate clock domains, where each clock domain can operate with its own clock frequency. Communication between the different clock domains are not trivial and must be handled with care. Several schemes can be used dep...
متن کاملThe Vlsi Implementation of 1d-dwt Based on Gals Systems
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 wavelet filter bank. The detailed design m...
متن کاملDesign of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems
Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...
