IPC: G06F9/06
Filed: 1992-03-27
Abstract: PURPOSE:To rationalize a range of permutation and to eliminate such manual set-back operation as the reinspection and the additional correction after permutation by sorting the identifiers based on the application attribute types and designating an attribute type in a permutation state. CONSTITUTION:When a certain identifier included in a program 5 is changed, a user inputs the identifier of a permutation subject, a desired permutation identifier, and a permutation subject type from an input device 3 and instructs the permutation processing. An identifier permutation processing part 7 refers to a type check table 6 based on the input permutation subject type to acquire the information on the relevant permutation subject range and carries out the permutation processing to change the permutation subject identifier into a permutation identifier in the permutation subject range. Thus, the user can designate the type of the identifier to be permutated so that the identifier of the desired type can be properly decided as a permutation subject. Thus, it is possible to eliminate such operations as the evasion, addition, etc., of permutation and to omit such manual set-back operations as the reinspection, the additional correction, etc.

Abstract: PURPOSE:To stably generate a timing signal by re-starting a counting means as considering under-mentioned time difference to be a starting time of counting when a time counting operation exceeds time corresponding to the regular arriving interval of a synchronizing signal and reaches the prescribed time. CONSTITUTION:At every first time corresponding to the arriving period of the synchronizing signal SYNC, a ten-bit counter 21 receives a clear pulse CLR to show the arrival of this synchronizing signal, and is operated to be cleared, and time-counts the time from '0' to ''910'. A decoder 25 monitors the count value of the ten-bit counter 21 counting the time after exceeding the first time '910', that is, the arriving period of this synchronizing signal, and detects a second time exceeding the first time '910', for instance, the point of time when the above-mentioned count value becomes '920'. Then, the decoder 25 preset-starts the counter 21 when this second time '920' is detected, and presets a counting start initial value '10' set beforehand according to the above- mentioned second time in the ten-bit counter 21. As the result, the counter 21 re-starts the counting operation of a clock signal CLK at the above-mentioned preset timing as considering the above-mentioned counting start initial value '10' to be a standard.
