Project-Oriented Approach to Low-Power Topics in Advanced Digital Design Course

Abstract

We consider a problem of low-power synthesis of digital systems, which are described as a Finite State Machine (FSM). In this paper, we apply FSM decomposition technique to organize the network as a collection of alternatively working components, thus greatly reducing the switching activity of the circuit (dynamic power management). To make a decision of decomposition task more tractable, corresponding CAD tools were developed at Tallinn University of Technology. Software tools are implemented using Java technology making them compatible with a wide range of operating systems and allowing a possibility for the remote access. Actually, developed system presents interconnection of CAD tools with e-learning methodology. The primary output of this work is the development of laboratory environment that provides students with extensive hands-on opportunities to enhance their knowledge and understanding of advanced concepts and principles in low-power digital design using FPGA technology and FPGA design suits. This can add a certain level of realism to the learning experience and helps to boost student’s motivation.
