Methods for Scheduling Read Commands and Apparatuses using the Same

摘要

A method for scheduling read commands, performed by a processing unit, including at least the following steps. Logical read commands are received from a master device via a first access interface, where each logical read command requests to read data of a logical address. First physical storage locations of mapping segments associated with the logical addresses are obtained from a high-level mapping table, and a second access interface is directed to read the mapping segments from the first physical storage locations of a storage unit. Second physical storage locations associated with the logical addresses are obtained from the mapping segments, and the second access interface is directed to read data from the second physical storage locations of the storage unit. The first access interface is directed to clock the data of the logical addresses out to the master device.

1. A method for scheduling read commands, performed by a processing unit, comprising:
receiving a plurality of logical read commands from a master device via a first access interface, where each logical read command requests to read data of a logical address; obtaining a plurality of first physical storage locations of mapping segments associated with the logical addresses from a high-level mapping table; directing a second access interface to read the mapping segments from the first physical storage locations of a storage unit; obtaining a plurality of second physical storage locations associated with the logical addresses from the mapping segments; directing the second access interface to read data from the second physical storage locations of the storage unit; and directing the first access interface to clock the data of the logical addresses out to the master device.
