Abstract
Described embodiments provide a method of allocating resources of a media controller for a data transfer. A data transfer request is received from at least one host device, and includes a host device ID and a data transfer request ID. The media controller generates a Tag ID of the data transfer request based on the host device ID and the data transfer request ID, and generates a starting memory address of a tag table based on the Tag ID of the data transfer request. A tag count value is read from the starting memory address of the tag table. If the tag count value reaches a threshold, an absence of a tag overlap is determined and the Tag ID of the data transfer request is added to the tag table at the starting memory address.
