| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Threshold Coupled Map, which has been proposed by S. Sinha, is a model in which plural processing elements that can generate chaos are connected each other via thresholding operation. In spite of using such a simple operation, this model can generate various spatiotemporal patterns, and its application to dynamical logic operation is also considered. We have designed a CMOS circuit realizing this model with current-sampling mode by using the pulse modulation approach. We have designed and fabricated an LSI chip that includes 30x30 elements with one-dimensional single/doubledirections and two-dimensional connections. Using the fabricated chip, we have obtained measurement results equivalent for the numerical calculation ones, and the measurement results of a one-dimensional array of 10 elements have demonstrated generation of various spatiotemporal patterns. | |
