摘要： PURPOSE:To suppress the number of comparators which require the detection of plural data values by providing a register to perform the bit designation of coincidence detection data. CONSTITUTION:In a detection data storage register 2, (5) or (D) is stored as detection data, and (7) is stored in a detection effective bit register 4 as effective bit designation data. At this time, since the content of the register 4 is (7), the comparison function of the fourth bit of the comparator 31 is nullified. Next, address information to be transferred to a BUSA is stored in a register 1 for storing data to be detected, and coincidence detection with the data value stored in the storage register 2 is performed at every timing. Here, since three low-order bits are effective for the coincidence detection, coincidence detection output CO from the comparator 31 goes to a level '1' when the data value of three low-order bits of the storage register 1 is set at (5).

摘要： PURPOSE:To operate a peripheral device at the optimum timing not depending on the dispersion of the transition time of an output signal by outputting a signal representing the determination of the output signal to the outside when the signal level of an output pin coincides with an output address signal in the inside of an LSI. CONSTITUTION:Address signals (a0-a31) on an internal bus are latched at a latch means LT by a timing signal phi2 via a transfer MOSQt of each of drivers (ADR0-ADR31). The signal is outputted to the output pins (A0-A31) after its driving force is increased by inverters INV3 and INV4 of two stages, however, the rise time of the signal is different according to load capacitance (C0-C31). The signals of the output pins (A0-A31) and that of the latch means LT are monitored by an EOX circuit, and when coincidence are obtained in all of the pins, the output of an OR gate G0 goes to a level '0', and a determination signal is outputted to the outside.

摘要： PURPOSE:To accelerate an unification processing by narrowing down an unification candidate thoroughly by switching the order of the arguments of both items which become the objects of comparison, comparing switched items with each other, and selecting the unification candidate by either comparison of the switched items. CONSTITUTION:In a selector which compares an item set in which plural items having the argument consisting of a variable or a constant is set as an element with a targeted item from the heads of both items sequentially and designates the items whose parts where the variables appear first coincide as the unification candidate, the order of the argument of the item set from a memory device 11 is changed at the argument order change processing part 13. And an unification candidate item is selected from the item set whose order is not changed and the targeted item at a unification candidate item selection processing part 12, and similarly, the unification candidate item is selected from both changed items at an unification candidate item selection processing part 14, and the unification candidate item is narrowed down thoroughly, and the output result of the processing part 13 or 14 whose processing is completed first becomes the unification candidate item. In such a way, the unification processing can be accelerated.

摘要： PURPOSE:To efficiently compare a large quantity of comparison data to detect a difference by adding information, which indicates the presence or the absence of a part, where a difference should be ignored though being detected as the result of comparison with an original record, and information of a code indicating the position of this part to each record of original data. CONSTITUTION:An input device 3 and an original record updating means 4 are provided, and information of the presence or the absence of the part where the difference as the result of comparison should be ignored, the part where the difference should be ignored, and the value of a mask code which substitutes said part with a specific code are inputted from the input device 3, and the original record updating means 4 adds information given from the input device 3 to the original record and records it in a comparison original record recorder 5 as a comparison original record. Records to be compared are inputted from the comparison original record recorder 5 and a comparison record recorder 6 and are compared with each other by a record comparing means 7, and information of disaccord is displayed on a result display device 8 if this comparison results in disaccord. Thus, comparison is efficiently performed to detect the difference in case of a large quantity of comparison data.

摘要： PURPOSE:To obtain a data processor having the fail-safe properties by securing such a constitution where the data received from processors are compared with each other via a comparator for each bit and an error detecting circuit stops the transmission of an alternating signal by a coincidence signal received in response to the discordance of said data comparison. CONSTITUTION:If some discordant bits are detected out of the data on data buses DB5 and 15, a discordance signal UAS is produced before generation of an end bit signal BES and a flip-flop FFC40 kept set is reset. Therefore an FFC39 is kept reset under such conditions and both outputs (g) and (h) are set 0. Hereafter an output (h) is not set at 1 but fixed at 0. Thus the transmission an alternating signal is stopped. if the FFC40 is kept reset when the signal UAS is produced, the FFC39 is kept set and the output (g) is kept at 1. Then the FFC40 is changed to a set state to set the output (h) at 1. Thus both FFC39 and 40 maintain the reset states hereafter and fix the output (h) at 1 to stop the transmission of the alternating signal. In such a way, the fail-safe properties are secured for a data processor.

摘要： PURPOSE:To realize detection of the coincidence among those data outputted in plural accesses by latching the data received from a data processor and comparing this latched data and the data received newly from the data processor with the comparison data respectively. CONSTITUTION:A single piece of data receives accesses via two continuous addresses, e.g., an N address and an (N+1) address. In such a case, the data on the N address is delivered from a data processor in the first access and latched by a latch circuit 4. Then the data on the (N+1) address is delivered from the processor 3 in the second access and latched by the circuit 4. These data latched by the circuit 4 are compared with the comparison data by a comparator 5 for detection of the coincidence among these data. In such a way, it is possible to detect the coincidence among those data delivered from the processor 3 in plural accesses.

摘要： PURPOSE:To execute binary and quaternary pattern matching with rapid response time only by one transistor by considering the property of matching operation at a gate level and executing all matching operations by complete parallel processing. CONSTITUTION:In a production system (PS), knowledge is described by if-then type and constituted of a condition part and an action part. The PS executes pattern matching between work memory (WM) for storing external information and the condition part of respective rules (PR), selects one of the rules succeeded in matching and executes the action part. A question is solved by repeating the recognition-action cycle. In the pattern matching, the condition part of a PR matched with the contents of the WM is rapidly detected. In order to attain rapid matching, complete parallel type architecture is adopted and the contents of the WM and PR are coded to binary and quaternary numbers.

摘要： PURPOSE:To debug a program efficiently even in a program loop by outputting a coincidence detection signal when a desired program address to be detected appears by as many times as specified. CONSTITUTION:An external specified value (n) (=m-1) is set in a counter 21 and a detection address on a signal line 12 is set in a register 11 so as to detect a program address which coincides with the desired detected address appearing by (m) times (m>0). A comparator 16 compares the held contents (detected address) of the register 11 with a program address led to an input B. When the number of times of appearance of coincidence reaches (n), the counted value of a subtracting counter 21 becomes 0. A NOR gate 26 makes a signal line 27 true and opens an AND gate and a matching signal MATCH2 coincides with the state of a matching signal MATCH1 outputted by the comparator 16. Namely, the signal MATCH2 becomes true for the first time after the comparator 16 detects the [n+1(=m)]th coincidence.
