Embodiments of the present invention disclose an access request scheduling method and apparatus. The method includes: receiving a to-be-enqueued access request, and determining a memory that the to-be-enqueued access request requests to access; writing the to-be-enqueued access request to one queue in one access queue group corresponding to the memory; selecting one candidate access queue from each candidate access queue group, as a to-be-scheduled queue; selecting, from the to-be-scheduled queues according to an access timeslot of each memory, alternative queues that can participate in scheduling in a current clock period; selecting, from the alternative queues, a specified queue in scheduling in the current clock period; extracting a to-be-scheduled access request from the specified queue; and granting an access authorization to the to-be-scheduled access request.
