Abstract
PURPOSE:To achieve high speed file accessing, by enabling to access a file in an auxiliary storage device only with a file name with a data processor. CONSTITUTION:In a controller 1, an interface 11 for data processor, a processor 12, a process memory 13, an associative memory 14, and a device controller 15 are mutually connected with a common data bus. The processor 12 is operated with the data for the program stored in the process memory 13 and manages the operation of the interface 11, the associative memory 14, and the device controller 15, and the entire system is functioned as an intelligent controller. A copy of table of contents in the auxiliary storage device 2 is stored in the associative memory 14.
