    • PURPOSE:To perform template matching at high speed by executing the pipeline processing of respective datum in parallel for at least one set of parallel input out of packet data consisting of word data of one or more words. CONSTITUTION:In a memory access control circuit 7, only one of memory access parts in memory readout parts 2A and 2B and memory write parts 5A and 5B is permitted to make access to a memory by a memory access permission signal. When contention is generated in plural number of memory access, the memory access is performed preferentially from the memory access part from which a request of memory access is issued earlier in the parts 2A, 2B, 5A, or 5B. The memory access part where the memory access is permitted generates a memory access execution signal representing a period to make access to the memory, and no permission of the memory access by other memory access parts is issued in the period of memory access. In such a way, the memory access of the memory access part from which another request of memory access is issued is permitted after completing the memory access under execution.

    • PURPOSE:To realize a fast template matching by providing a pre-detecting part and a template matching part, and executing the pipeline processing of respective data for data on parallel data transmission paths in parallel. CONSTITUTION:When it is recognized that the flag of the data in the template matching part 2 shows the coincidence of identifiers by comparing the identifiers of the data between confronting data transmission paths at the pre-detecting part 1 and attaching a decision result flag, and when both data make access to the same memory address and a low priority is attached, no access to a matching memory is performed, and frequency to make access to the memory is decreased. In case of generating contention in the access to the data when second readout by the data on the other side is performed by the time when write is performed after performing first readout by the data on one side between different data transmission paths, it is decided that second data read out later is not correct. In such a way, a decision flag makes the access to the matching memory by the data with the low priority wait.

    • PURPOSE:To improve the whole processing capacity of a system by transmitting data on a data transmission path as processing by a transmission time proper to the data transmission path, and setting the applying time of the data smaller than a processing time in each means. CONSTITUTION:The number of stages of the data transmission path is fitted so that a time required for the comparison decision of the data can be set equal to the time at which the data is transmitted from a comparison section A or B. Therefore, it is possible to process transmitted data by a data processing part 4A or 4B provided between the stages of the data transmission path according to the compared result of a comparison decision part 3. When the time required for the processing of the data is larger than the transmission time proper to the data transmission path, the functional constituent of the processing is divided and arranged so that the time required for the processing can be set less than the time proper to the data transmission path, then, a pipeline processing is performed. In such a way, it is possible to process the data without disturbing the transmission of the data.

    • PROBLEM TO BE SOLVED: To set the optimum latency for the power supply potential by selecting a predetermined mode register within a plurality of mode registers to which different operation modes are set depending on a power supply potential detecting signal from a power supply potential detecting circuit. SOLUTION: Different operation modes are set to mode registers 411 to 41n of a mode setting means 19. A mode register selecting circuit 42 detects a power supply potential of a memory and controls a selector 43 with a selection signal Sn depending on the level of the power supply potential, causing it to output any one of the output signals (operation mode signals) MD1 to MDn from the mode registers 411 to 41n to a control logic 18 as a selected output signal SS. Thereby, the optimum latency, etc., can be set depending on the power supply potential and complication of manufacture and product control can be eliminated without requiring preparation of devices in different operation modes for each specification of the devices.
