METHOD FOR THE FAIR DATA TRANSFER IN A SHARED BUS BY MEANS OF A DISTRIBUTED ARBITRATION ALGORITHM

摘要

Method to transfer data among different modules of a system connected by a shared bus, particularly to obtain a continuous and without inactive period fairly shared use of resources among the modules themselves under traffic-jam conditions, which employs a distributed arbitration algorithm, that can be implemented on both hardware and software of the different modules of the system. This algorithm ensures a fair and weighed access of the data to the shared bus interconnecting the modules, the weight relating to each module/flow being monitored through tags. Said tags are applied to the data flows entering each module, in order to monitor the access to the shared bus.
