STORAGE DEVICE AND COMMAND CONTROL METHOD

摘要

[Problem] To propose a storage device and a control method whereby it is possible to achieve improvement in processing speed in a storage device whereupon a plurality of microprocessors are mounted. [Solution] Provided is a storage device whereupon a plurality of microprocessors are mounted, comprising: a virtual queue which stores a virtual command which is used within the storage device; an actual queue which stores an actual command based on a real communication protocol; a first pointer which is updated when the virtual command is stored in the virtual queue; a second pointer which is updated when the first pointer is updated; a check unit which senses the updating of the first pointer and updates the second pointer; and a control unit. Upon sensing that the second pointer has been updated by the check unit, the control unit queries the second pointer and the first pointer, reads out the virtual command which is stored in the virtual queue, converts same to the actual command, and stores same in the actual queue.
