Abstract
A timing method and a timing device are disclosed. A Gray code count output may be obtained by performing a Gray code count on a basic clock. Then m number of sub-clocks may be obtained by separately performing a phase shift on a least significant bit output of the Gray code count output, where a phase difference φ between each of the m number of sub-clocks and the least significant bit output may satisfy: φ=n×α and φ≠90°, 180° may be divisible by α with no remainder, and n may be an integer greater than 0 and less than 180°/α. If 90° is divisible by α with no remainder, m=180/α−2; and if 90° is divisible by α with a remainder, m=180/α−1. When a predetermined event occurs, a timing result of the predetermined event may be obtained according to the Gray code count output value, outputs of the m number of sub-clocks, a period of the basic clock, and the α.
