Chaos-based RNGs have become an alternative method for random number generation (RNG) which is the vital part of the security hardware. When full-digital implementations of a chaotic system are considered, a periodic limit cycle with a large period appears. In order to reverse this degradation in dynamics of chaotic time-delay sampled system, the digital circuit has been supported by delaying buffers...
A new true random bit generator circuit which is a time-delay sampleddata feedback system is proposed. The differential equation that defines the dynamic behaviour of the circuit is implemented by analogue active and passive components with a digital block that forms the sample and hold delay line as the feedback. A D-type flip-flop chain is used on the delayed feedback line due to the feedback signal...
In this demo, we introduced a mobile robot navigation test setup that is accessible via internet. This test setup has a Lego Mindstorms NXT differential drive mobile robot which is controlled by a computer with Bluetooth connection. The control computer, which is called Host Computer in Fig. 1, runs MATLAB to operate the system. The navigation of mobile robot is based on an algorithm which uses a...
This paper introduces an active wave computing based algorithm for real-time robot navigation problem in dynamically changing environment and presents a real test setup with a roving robot. Travelling waves propagated on Cellular Neural Network (CNN) were employed by the system to find the shortest path as proposed in our previous work. The setup has a ceiling camera which captures an image of the...
In this demo, we will introduce a hardware based on Xilinx XC2VP30 FPGA chip on the Xilinx University Program Virtex-II Pro Development System for studying spatiotemporal waves in real-time. The network which is implemented on the FPGA is a two dimensional reaction-diffusion Cellular Neural Network consists of relaxation oscillators. The network can be programmed to generate spatiotemporal waves....
This paper introduces a digital implementation of a new simple programmable autowave generator network on a field programmable gate array (FPGA). The network is a two dimensional reaction-diffusion Cellular Neural Network which consists of relaxation oscillators. The introduced implementation successfully simulates 25,600 neurons in real-time with novel Cellular Neural Processing Network architecture...
