Abstract
Disclosed is a data caching method, comprising: according to an input port number of a cell, storing the cell in a corresponding first-in first-out queue; determining that a cell to be dequeued can be dequeued in the current Kth cycle, scheduling for the cell to be dequeued to be dequeued, acquiring the actual value of the number of splicing units occupied by the cell to be dequeued, and storing the cell to be dequeued in a register the same number of bits wide as a bus in a cell splicing manner, wherein determining that the cell to be dequeued can be dequeued is conducted in accordance with the fact that a first back pressure count value of the (K−1)th cycle is less than or equal to a first preset threshold value, and the first back pressure count value of the (K−1)th cycle is obtained in accordance with an estimated value of the number of the splicing units occupied when the previous cell to be dequeued is dequeued, the number of splicing units capable of being transmitted by the bus in each cycle, and a first back pressure count value of the (K−2)th cycle. Also disclosed at the same time are a data caching device and a storage medium.
