Processing system and method for detecting hotkey activation

A processing system for detecting hotkey activation, for allowing a computer device to determine whether a hotkey of a keyboard is activated by a user so as to initiate a hotkey activation program in the computer device to execute an application program corresponding to the hotkey if being activated, the processing system for detecting hotkey activation comprising:

• a controller electrically connected to the keyboard and for detecting a keying signal generated corresponding to the hotkey of the keyboard being activated by the user;
• a processor electrically connected to the controller and for executing a corresponding process according to the keying signal detected by the controller;
• a first register comprising a plurality of bits, each of the bits corresponding to each hotkey provided by the keyboard respectively;
• and
• a second register comprising a plurality of bits, each of the bits corresponding to each hotkey provided by the keyboard respectively,
• wherein when the controller detects activation of the hotkey of the keyboard, the controller sets the bits, which correspond to the hotkey, in the first and second registers, to allow the hotkey activation program to detect via polling the corresponding bit of the first register being set, and allow the processor to execute the application program corresponding to the hotkey, and wherein when the controller detects the hotkey being released, the controller alters a value of the corresponding bit of the second register being set, to allow the hotkey activation program to detect via polling that the hotkey has been released.
