Next, please refer to the block diagram of the embedded playback system provided by the present invention shown in FIG. 2 . In the architecture shown in FIG. 2 , it is mainly composed of a user interface program 202 , an embedded core module 204 , a processor 206 , a memory 208 , an optical disc player 210 , and a display device 212 . In addition, the embedded core module 204 further includes a schedule management module 2042, a memory management module 2044, and a playback device driver module 2046, which are respectively interposed between the user interface, the processor 206, the memory 208, and the optical disc playback device 210. time, to receive the instructions input by the user through the user interface program 202, and send the instructions to the processor 206, the memory 208, the optical disc player 210 and other hardware for processing, and then output the processing results to the display device 212, For example, a liquid crystal display (LCD) or a cathode ray tube (CRT) is used for display. In fact, the processor 206 and the memory 208 are all coupled with the schedule management module 2042, the memory management module 2044, and the player drive module 2046 in the embedded core module 204, except that the optical disc player 210 can read from the memory In 208 , the processor 206 can control and manage the process executed by the optical disc player 210 in addition to obtaining the optical disc data information and the program code of the player driving module 2046 .

It should be noted that the processor 206 can use the central processing unit (CPU) of the computer system, and the memory 208 can use various memories of the computer system to perform required operations, and the optical disc player 210 can be a CD-ROM player. ROM, VCD or DVD player (Player). Furthermore, the schedule management module 2042 includes the creation and removal of the schedule (Process) related to the optical disc player 210 (Process), the external I/O connection of the schedule, the schedule management (Scheduler), and the schedule. Inter Process Communication (IPC), as well as some program codes related to computer architecture, are used to provide a multitasking (Multitasking) environment for multiple processes to be performed simultaneously on the processor.

Furthermore, the modules shown in Figure 2 can also be constructed by using C/C++ to write the required program codes. However, it is more convenient to use embedded Linux because the current Linux source codes are all free public program codes. , and using C/C++ to write the program code will need to rewrite the new program code, which requires more manpower.

Next, please refer to FIG. 3 for the operation flowchart of the embedded playback system of the present invention. First, after the computer system starts the embedded player system (step 302), the embedded player system will read the system resources such as the input/output interface (I/O port) and the interrupt channel (InterruptR60uest, IRO) of the optical disc player 210 (step 302 ). 304), then load the driver of the optical disc player 210 (step 306), then close the device that does not need to play the optical disc data information, such as the power supply of the hard disk (step 308), and finally read out the disc from the optical disc data and play (step 310). In embedded Linux, the purpose of reading system resources such as I/O interfaces and IRQ can be easily accomplished through the request/free function provided by the system, or the registration of I/O interfaces can be queried through the "/proc/ioports directory" Data information, and use request_irq and free_irq algorithms to obtain and release IRQ. In addition, because the hard disk does not provide much support when the operating system is not started, and only the application of the optical disc player is started, it can be loaded into the memory as the driver of the optical disc player 210 stored in the hard disk. After 208, turn off the power of the hard disk to complete the purpose of power saving.
