COLLECTING AND HOLDING SYSTEM OF RAS INFORMATION IN DATA WAY SYSTEM

摘要

PURPOSE:To reduce the memory capacity and at the same time to shorten the collecting/allotting time, by holding in a hierarchical structure of the detailed RAS information inherent to own station and the generalized RAS information related to all stations at each station. CONSTITUTION:A station 1 includes a memory block 10 which stores the detailed RAS information intrinsic to the corresponding station plus memory blocks 11 and 12 that store the generalized RAS information related to all stations within a system. The detailed constitution information 10a of the memory 10 is produced at the moment when the data way control part of the station recognizes a change of the constitution; and the detailed channel information 10b is produced when the internal state of the constitution element of the station has a change, respectively. At the same time, the working information 10c is produced when the constitution element of the station sets the prescribed working to the corresponding region.
