REAL TIME PROCESSING SYSTEM

摘要

A real time data processing system consisting of a plurality of processing nodes (NODE1, NODE2, NODE3) and a write only reflective data link (46) for transferring information containing writes only between the plurality of processing nodes (NODE1, NODE2, NODE3). All the nodes (NODE1, NODE2, NODE3) include a bus (22), a processor (20) coupled to the bus (22), a memory (40) having at least two ports with one port (42) connected to the bus (22) and the other port (48) connected to the data link (46) and a sensor (60) for sensing a write to the memory (40). At least one node has a VME bus (22) as the bus (22) and serves as an I/O connected to one port (42) of the memory (40). Further a local bus (24) is included for inputting and outputting from the memory (40). The local bus (24) is connected to a third port (44) of the memory (40).
