METHOD OF GENERATING CLOCK AND SEMICONDUCTOR DEVICE |
摘要 |
A method of generating a clock includes the steps of calculating a first frequency division number through dividing a frequency of an input clock by a target frequency and a specific integer k (k≧2); calculating a second frequency division number according to the first frequency division number; dividing a period of time of one cycle of the target frequency by the specific integer k to obtain sections in a number of the specific integer k; dividing the frequency of the input clock with the second frequency division number within one of the sections; dividing the frequency of the input clock with the second frequency division number within each remaining one of the sections in a number of (k−1); and generating the clock having a frequency with one cycle equal to a period of time corresponding to each of the sections. |

1. A method of generating a clock, comprising the steps of:
calculating a first frequency division number through dividing a frequency of an input clock by a target frequency and a specific integer k (k≧2); calculating a second frequency division number according to the first frequency division number; dividing a period of time of one cycle of the target frequency by the specific integer k to obtain sections in a number of the specific integer k; dividing the frequency of the input clock with the second frequency division number within one of the sections; dividing the frequency of the input clock with the first frequency division number within each remaining one of the sections in a number of (k−1); and generating the clock having a frequency with one cycle equal to a period of time corresponding to each of the sections in the number of the specific integer k obtained through dividing the frequency of the input clock. |
