Abstract: Disclosed are a method and an apparatus for eliminating a glitch, and a state machine, which are used for improving the accuracy of data transmission. The method includes: acquiring a transmission instruction of to-be-transmitted data, the transmission instruction at least carry the data; when it is determined that a first slave state machine can transmit the data, transmitting the to-be-transmitted data to the first state according to the transmission instruction; transferring the data according to a preset transfer state; when it is determined that a clock cycle for transmitting the data reaches a preset clock cycle, transferring the to-be-transmitted data to a preset state; and when it is determined that a preset transmission time is reached, transmitting the data.
