    • A data base information engine subsystem which examines data on the fly as it is retrieved from a mass storage device (i.e., disk), and before storing it in memory, to select only the specified elements of data required by the host computer according to criteria set forth by the host computer. A page mapper circuit separates the host command processing from the data access processing for the command. The instruction set used by the information engine subsystem contains optimizing algorithms to parse and reorder the required operation to be most efficient (with respect to time). The information engine subsystem also contains a high speed processor which is a special purpose processor designed and optimized for data retrieval while doing operations on the data at high speed.
    • 数据库信息引擎子系统,在从大容量存储设备(即,磁盘)中检索数据时,检查数据,并且在将其存储在存储器中之前,仅根据标准选择主计算机所要求的指定数据元素 由主机提出。 页面映射电路将主机命令处理与命令的数据访问处理分开。 信息引擎子系统使用的指令集包含优化算法,用于解析和重新排序所需的操作以最有效(相对于时间)。 信息引擎子系统还包含一个高速处理器,它是专门为数据检索而设计和优化的专用处理器,同时对数据进行高速操作。
