The present disclosure relates to a method for implementing processing elements in a chip card such that the processing elements can communicate data between each other in order to perform a computation task, wherein the data communication requires each processing element to have a respective number of connections to other processing elements. The method comprises: providing a complete graph with an even number of nodes that is higher than the maximum of the numbers of connections by one or two. If the number of processing elements is higher that the number of nodes of the graph, the graph may be duplicated and the duplicated graphs may be combined into a combined graph. A methodology for placing and connecting the processing elements may be determined in accordance with the structure of nodes of a resulting graph, the resulting graph being the complete graph or the combined graph.
