This paper presents a state assignment method oriented to reduction of power consumption in Finite State Machines. The proposed algorithm is based on creating a binary tree whose nodes are created by sharing a finite state automaton. The experimental results show that the proposed algorithm leads to the reduction in power consumption compared to the state encoding algorithms have already been developed. The reducing of circuits' area is observed too.


In the paper there is presented a novel method of asynchronous data exchange between locally synchronous blocks of a GALS system. The method is oriented toward the minimization of power consumption within complex image or video compression designs. The solution is based on implementation of the asynchronous modules for individual functional blocks of the encoder, which are equipped with asynchronous interfaces and enable gating of a local clock signal. In the article there are presented experimental results obtained after adopting the method in the Motion JPEG2000 encoder design.


This paper describes influence of the multilayer PCB layout on radiated emissions level and quality of signals in the circuit. Numerical methods are used for analysis of radiated emissions level from a few testing PCB's excited by real digital waveforms.
