Filed: 1988-09-22
Abstract: PURPOSE:To decrease the data transfer frequency between a CPU and a memory device and to improve the system throughput by retrieving data within the memory device after giving only the goal literal to the memory device and therefore retrieving data with no dependence on the CPU. CONSTITUTION:The literals 1-10, i.e., the sets of data consisting of plural optional items serving as the units of information which are stored or processed in a logical language are stored and controlled by a memory device in a data structure suited to the retrieval of data. When these literals are read out, the goal literal is directly received from a CPU and a literal having a pattern matched with the goal literal is retrieved by the hardware stored in the memory device. Thus the data can be retrieved at a high speed with no dependence on the CPU and at the same time the data transfer frequency is decreases between the CPU and the memory device. Then the throughput of a logical language process system is improved.
