Neuromorphic circuits will be considered for energy efficient computing based on biological principles in future electronic systems. Thereby, memristors are assumed in neuron models and for synapses in several recent investigations in order to overcome the limits of conventional von Neumann architectures by taking these devices as memory elements as well as devices for computation in bio-inspired artificial neural networks. Recently, an implementation of a cross-bar array of resistive memory devices has been applied for the detection of temporal correlations between event-based data streams. Furthermore, Memristor Cellular Neural Networks (M-CNN) are universal high-speed computing systems with stored programmability and are also based on the principle of distributed computing with memory. The dynamical behavior of these spatio-temporal systems will be exploited to solve multidimensional signal processing and classification problems. For example, reaction-diffusion systems can be represented by state equations of so-called reaction-diffusion CNN showing the emergence of complex behavior (e.g. pattern formation) based on local activity and especially on a parameter subset called the “edge of chaos”.
A detailed introduction into the theory of memristors will be provided and recent applications discussed in detail. Furthermore, M-CNN will be proposed as sensor-processor structures allowing the application of deep learning in future information processing systems. Finally, a memristor-enhanced robot control system will be introduced and the performance in movement control evaluated for different cases.
