Abstract

Disclosed are an asynchronous FIFO read/write control method and system, and an electronic device, belonging to the technical field of data read/write technology. The asynchronous FIFO read/write control method comprises: parsing data received by a front-end interface to obtain a data packet length and valid video data; determining an almost empty threshold of a first FIFO queue and a second FIFO queue according to the data packet length, and writing the valid video data into the first FIFO queue and the second FIFO queue in a ping-pong manner; determining a minimum time interval of FIFO readings according to a sending time sequence of a back-end interface, and reading data from the first FIFO queue and the second FIFO queue in the ping-pong manner according to the almost empty threshold and the minimum time interval, so as to output the read data through the back-end interface.
