Abstract
PURPOSE: To obtain a file data processor that provides high-speed retrieval processing by setting various comparison conditions for one piece of information and then by making simultaneous comparisons.
CONSTITUTION: Processor (CPU)1 is connected to main memory unit (MS)5 and file unit (DSC)3 such as a magnetic disk unit through channel (CH)2. Between CH2 and DSC3, file data processor (FDU)4 is connected. Then, FDU4 retrieves only data, meeting various conditions, among data read out of DSC3 successively and transfers the data to the main memory unit. Here, FDU4 can easily be constituted by providing comparing circuits.
