Abstract

The distributed data handling and processing resources system of the present invention includes a) a number of data handling and processing resource nodes that collectively perform a desired data handling and processing function, each data handling and processing resource node for providing a data handling/processing subfunction; and, b) a low latency, shared bandwidth databus for interconnecting the data handling and processing resource nodes. In the least, among the data handling and processing resource nodes, is a processing unit (PU) node for providing a control and data handling/processing subfunction; and, an input/output (I/O) node for providing a data handling/processing subfunction for data collection/distribution to an external environment. The present invention preferably uses the IEEE-1394b databus due to its unique and specialized low latency, shared bandwidth characteristics.
