    • 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 object numbers. Also disclosed are object tables in digital data processing systems of the present invention involving a single memory and multiple processors and pointers and pointer to logical address conversion means in digital data processing systems of the present invention.
    • 一种包括处理器和存储器并采用对象寻址的数字数据处理系统。 数字数据处理系统还包括用于将系统的存储器组织成对象的系统和用于操作存储器的系统。 存储器组织系统将存储在存储器中的每个数据项与对象和每个对象与对象标识符相关联。 存储器操作系统响应于从处理器接收到的存储器操作说明符而对数据项执行存储器操作。 要执行存储器操作的数据项的位置由逻辑地址指定。 每个逻辑地址包含与一个对象标识符临时相关联的对象号,以及指定由当前与对象号相关联的对象标识符标识的对象中的位置的偏移。 存储器操作系统包括单个对象表,其指定对象号和通用地址之间的当前临时关联,以及对象标识符转换系统,其建立对象表中的临时关联并获得与对象号相关联的对象标识符。 还公开了本发明的数字数据处理系统中的对象表,其涉及单个存储器和多个处理器以及指向本发明的数字数据处理系统中的逻辑地址转换装置的指针。
