ABSTRACT:
A real time data processing system in which each of a series of processing nodes is provided with its own data store partitioned into a first section reserved for the storage of data local to the respective node and a second section reserved for the storage of data to be shared between nodes. The nodes are interconnected by a data link and whenever a node writes to an address in the second section of a data store the written data is communicated to all of the nodes via the data link. The data in each address of the second sections of the data stores can be changed only by one respective processing node which acts as a master for that address. As each address containing shared data can only be written to by one node collisions between different nodes attempting to change a common item of data cannot occur.
