APPARATUS AND METHOD FOR DECOR-DEPENDENT DATA PROCESSING SYSTEM

摘要

In a data processing system including a central processing unit capable of operation with a plurality of operating systems a VMSM unit is described for producing a composite decor descriptor from a plurality of possible decor descriptor formats. The VMSM unit includes an input buffer unit and an output buffer unit, a control unit to analyze an incoming DATA and provide approprite control signals, a reconfiguration unit for reformatting the plurality of descriptor formats into a composite format, a descriptor fetch unit for retrieving a descriptor when the signals applied to the VMSM unit contain a descriptor address, and a descriptor master copy unit which contains a copy of the descriptors stored in the addressing apparatus.
