In this paper, a new method is introduced to implement chaotic generators based on the Henon map and Lorenz chaotic generators given by the state equations using the Field Programmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic generators. The new method is based on the MATLAB® Software, Xilinx System Generator, Xilinx Alliance tools and Synplicity Synplify.

This software is developed to provide ease with controller design. For PID control, options are given to design and analyse the compensated and uncompensated system. You are free to choice among Proportional PI, PD and PID mode of control. Both frequency and time domain characteristics can be observed. Special Menus are given to observe time and frequency response plots. For Statefeedback controller similar options are given. But this is limited to second order system only.

This sample program generates two sine waves called X and Y. It will then calculate the normalized magnitude and phase of the two waveforms using the following formulas: Mag = sqrt(X^2 + Y^2)/sqrt(GainX^2 + GainY^2) Phase = (long) (atan2PU(X,Y) * 360) The program will prompt the user to change the gain and frequency of the X and Y waveforms.

Abstract—We describe a technique for image encoding in which local operators of many scales but identical shape serve as the basis functions. The representation differs from established techniques in that the code elements are localized in spatial frequency as well as in space.
