Title:
PROGRAMMABLE FREQUENCY DIVIDER AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/094924
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention are a programmable frequency divider and a computer storage medium. The programmable frequency divider comprises: a state machine unit configured to control a state transition when an input clock source period expires, and to output a clock signal representing a state of the state machine unit on the basis of the state transition, wherein the number of states of the state machine unit is adapted to a frequency division number; a logic unit configured to obtain the clock signal representing the state of the state machine and to output a control signal to the clock output unit, wherein the output control signal is used for controlling the clock signal output from the clock output unit to turn over when the state of the state machine meets a preset state, and the logic unit is also configured that when the frequency division number is an odd number, the output clock signal is controlled to be subjected to a duty ratio correction; and a clock output unit configured to output a frequency-division clock signal with equal duty ratio when a frequency division number is even; When the frequency division number is an odd number, the output clock signal is controlled to be subjected to the duty ratio correction, to output a frequency-division clock signal with equal duty ratio.
