Next, the hardware and software are planned and divided (step S102). Then, new peripheral circuit design and circuit layout (step SH) 3 and step S1⑷ are started. When designing or completing the hardware, developers must learn the operating system core, system driver development tools (DDK), and system application programming interface (API) (step s1Q5) used by the system, and then develop related drivers Program (step S106), and test the performance of the driver (step S 107). When the performance of the driver is not good, you must redesign the hardware or replace the new operating system, especially when developing the driver of another operating system, you must repeat the learning system driver development tools, system application program interface, and Development of drivers and other tasks (for example: learning WinCE operating system takes 3_6 months), and delaying the development of new products and causing additional burdens. In addition, the current development driver tools only support Microsoft products (Windows series), not the ability to span multiple operating systems, and fail to meet the needs of embedded systems.

Description of the invention (5) Card service function set and resource management service function set. Expansion card data tools Function sets are used to access expansion card CIS and register data and other functions. Expansion card service function set is used to report expansion card service information, registration information, and status information, or to perform functions such as reset and object mask setting. ◦ Resource management service function set is used to check and configure system resources. Among them, the system resources include memory, interrupt request (IRQ), direct memory access (DMA), and I / O address, etc. Application programming interface (API) module 22 provides the above three functions in addition to Wai 'is also linked with the complex array function library in the operating system 25, and is provided for linking with the General Peripheral Driver Module (GPDD) 21 through the linked function library, so that the driver developer can In the User Mode, the expansion card service is developed by the application program interface module 22, that is, the self-developed module 2 6 is used, for example, access to expansion card related functions, access to system resources, specific function modules, and requirements.
