Abstract
A controller for processing a command in a data storage device includes at least one bitmap and a firmware command que. The at least one bitmap is formed in hardware to indicate that the command is received. The firmware command que is generated by firmware for storing the command when the at least one bitmap indicates receipt of the command. The firmware generates the firmware command que that is of variable size for processing a high number of commands. In addition, the bitmaps are generated in the hardware for quickly receiving the high number of commands.
