Abstract
A digital data processing system including a processor and memory and employing object addressing. The digital data processing system further includes a system for organizing the system's memory into objects and a system for operating the memory. The memory organization system associates each item of data stored in the memory with an object and each object with an object identifier. The memory operation system performs memory operations on items of data in response to memory operation specifiers received from the processor. The location of a data item upon which a memory operation is to be performed is specified by a logical address. Each logical address contains an object number which is temporarily associated with one object identifier and an offset specifying a location in the object identified by the object identifier currently associated with the object number. The memory operation system includes a single object table which specifies the current temporary associations between object numbers and universal addresses and an object identifier conversion system which establishes the temporary associations in the object table and obtains the object identifiers associated with the o…
