The disclosure describes a data enqueuing method. The method may include: receiving a to-be-enqueued data packet, dividing the data packet into several slices to obtain slice information of the slices, and marking a tail slice of the data packet with a tail slice identifier; enqueuing corresponding slice information according to an order of the slices in the data packet, and in a process of enqueuing the corresponding slice information, if a slice is marked with the tail slice identifier, determining that the slice is the tail slice of the data packet, and generating a first-type node; and determining whether a target queue is empty, and if the target queue is empty, writing slice information of the tail slice into the target queue, and updating a head pointer of a queue head list according to the first-type node.

Data enqueuing method, data dequeuing method, and queue management circuit

Embodiments of the present invention provide a method and a device for writing data. The method includes: receiving a data block that is to be written in an EDRAM; obtaining, according to a status of a bank in the EDRAM, usable addresses corresponding to usable banks in the EDRAM; selecting an address from the usable addresses as a write-in address of the data block; and writing the data block in a bank corresponding to the write-in address. In the embodiments of the present invention, problems in the prior art that a conflict occurs when a data block is written in a bank and a conflict occurs when a data block is read from a bank can be avoided, and working efficiency of the EDRAM is improved.
