Launch device for electronic apparatus and method thereof
A launch device for launching an electronic apparatus comprises a storage unit, a main storage and a processor. The storage unit is configured to store a mini-launch code for executing a detection of an output value of a sensor, and store system driving codes which comprises a standard launch code for launching electronic apparatus. The main storage loads the mini-launch code and the system driving codes. The processor loads and executes the mini-launch code or the standard launch code.
1. A launch device for launching an electronic apparatus, comprising:
a storage unit configured to separately store a mini-launch code and system driving codes for driving the electronic apparatus, the mini-launch code for detecting an output value of a sensor that is internal or external to the electronic apparatus;
a main storage configured to load the mini-launch code and the system driving codes; and
a processor configured to read and transfer at least one of the mini-launch code or the system launch codes to the main storage, and configured to execute the mini-launch code or the system launch codes,
wherein the storage unit comprises a first storage for storing the mini-launch code and a second storage for storing the system launch codes, and
wherein bandwidth of the first storage is wider than bandwidth of the second storage.
2. The launch device for launching the electronic apparatus according to claim 1 , wherein the system launch codes include a standard launch code for launching the electronic apparatus and an operating system image.
3. The launch device for launching the electronic apparatus according to claim 2 , wherein the standard launch code includes an initialization code for initializing hardware of the electronic apparatus and a loading code for loading the operating system image.
4. The launch device for launching the electronic apparatus according to claim 1 , wherein the processor executes the mini-launch code for detecting the output value of the sensor, determines whether the output value of the sensor meets a predetermined condition, and executes the standard launch code when the output value of the sensor meets the predetermined condition.
5. The launch device for launching the electronic apparatus according to claim 1 , wherein the processor executes the mini-launch code periodically according to a predetermined period set by an internal counter disposed in the electronic apparatus.
6. The launch device for launching the electronic apparatus according to claim 1 , wherein the processor detects an operational status of the sensor, turns on the sensor when the power of the sensor is switched off, and detects the output value of the sensor.
7. A launch method for launching an electronic apparatus, comprising:
periodically receiving a wake-up signal by utilizing a processor;
loading a mini-launch code for detecting an output value of a sensor into a main storage after receiving the wake-up signal, wherein the sensor is internal or external to the electronic apparatus;
loading a standard launch code for launching the electronic apparatus and a system driving code into the main storage, wherein the system driving code comprises an operating system image; and
executing the mini-launch code or the standard launch code by utilizing the processor,
wherein the mini-launch code is stored in a first storage and the system driving code is stored in a second storage, and
wherein bandwidth of the first storage is wider than bandwidth of the second storage.
8. The launch method for launching the electronic apparatus according to claim 7 , further comprising: detecting the output value of the sensor by utilizing the processor to execute the mini-launch code, and determining whether the output value of the sensor meets a predetermined condition; and
executing the standard launch code when the output value meets the predetermined condition.
9. The launch method for launching the electronic apparatus according to claim 8 , further comprising:
periodically transmitting the mini-launch code to the processor according to a predetermined period set by an internal counter of the electronic apparatus.
10. The launch method for launching the electronic apparatus according to claim 8 , further comprising:
detecting an operational status of the sensor, and turning on the power of the sensor when the power of the sensor is switched off.
11. The launch method for launching the electronic apparatus according to claim 7 , wherein the standard launch code includes an initialization code for initializing hardware of the electronic apparatus and a loading code for loading the operating system image.
