Problems solved by technology

The current BIOS POST process is designed for a specific hardware configuration. If you need to configure the BIOS for different embedded systems, you need to modify the source programs related to Chipset and SuperI / O in the POST process, and may even modify the entire program. The structure of the BIOS needs to be adjusted, which not only makes the development and configuration of the BIOS a lot of work, takes a long time, and is prone to errors

Embodiment Construction

[0019] see Figure 2-6 , the present invention provides a structured design method of POST in a PC framework embedded system, which is composed of the following steps: (1) define the data structure according to the data type and the operation type of Chipset and SuperI / O initialization information, and initialize by definition The information is formatted as initialization data; (2) Store the initialization data in the initialization data table area; (3) The initial address of each group of data tables in the initialization data table area is dynamically allocated, and the initialization data vector table is set to store each group of data in order The entry address of the table; (4) set the corresponding initialization subroutine according to the data structure of the initialization information. The POST process is actually composed of a series of detection work and some instruction sequences that write specific data into designated hardware registers. Except for the initial...

Abstract

The invention discloses a method for designing upper electric self-checking of a PC frame embedded system, which is formed by the following steps: (1) defining data structure by the data type and operation type of the Chipset and Super I / O initial information, formatting the initial information to initial data; (2) storing the initial data into the initial data form; (3) adopting dynamic allocation to each group of data form initial address of the initial data form area, arranging initial data vector list to store the inlet address of each group of data form; (4) arranging the corresponding initial subprogram by the initial information data structure.

Description

technical field [0001] The invention relates to the field of computer development, in particular to a design method for power-on self-check in an embedded system with PC architecture. Background technique [0002] Embedded computer systems can have different architectural forms with different application methods. Embedded computers with PC architecture, because they use the same hardware structure, software operating system and software development platform as standard PCs, are easy to develop and have abundant application program design resources, so they occupy an increasing share in embedded systems, especially It has been widely used in industrial control and military fields. [0003] Unlike consumer electronic products with no operating system and single function, the structure of embedded computers with PC architecture is derived from PC (personal computer), and its functions are complex. Initializing hardware and booting the operating system are still controlled by B...
