In steps S11 and S13, the basic input/output system 11 reads external files from the external file database 13 and retrieves chip information from the chip 5. It should be particularly explained here that the sequence of steps S11 and S13 in FIG. 3 is only shown as an example. In other embodiments, the basic input/output system 11 can first retrieve chip information and then read external files. Two data can be read at the same time. In step S15, the basic input/output system 11 executes a chip identification process based on external files and chip information to obtain chip identification results.

The wafer identification process in step S15 is described in detail, and it may include steps S151 to S157 in FIG. 4. As described above, the external file stored in the external file database 13 may include multiple chip series data, the multiple chip series data includes multiple chip segment data, and the multiple chip segment data includes multiple The device ID code data is similar to the concept of storing multiple device ID code data in multiple layers of folders, and each of the multiple device ID code data includes a corresponding device ID code name. In step S151, the basic input/output system 11 determines that the chip information belongs to one of a plurality of chip series data, and the one of them is used to determine the chip series data. In step S153, the basic input/output system 11 determines that the chip information belongs to one of the plurality of chip segment data in the discriminating chip series data obtained in step S151, and uses this one as the discriminating chip segment data. In detail, the basic input/output system 11 will use the device information and the manufacturer’s identification code (ID) in the PCIE configuration setting space of the multi-function input/output (I/O) controller supporting the ISA device bus in the chip information. The information is compared with the multiple chip segment data in the discriminating chip series data to determine the discriminating chip segment data to which the chip information belongs. In step S155, the basic input/output system 11 determines that the chip information belongs to one of the plurality of device identification code data in the discriminating chip segment data obtained in step S153, and uses the one of them as the device identification device Code information.

In detail, step S17 of FIG. 3 may include steps S171 to S175 shown in FIG. 5.

In step S171, the basic input/output system 11 obtains control pin start data and control pin interval data corresponding to the chip identification result. In step S173, the basic input/output system 11 selects the pin corresponding to the start data of the control pin in the universal input/output port 211, and starts to configure the pin (for example, setting its potential level). After the configuration of the pin selected in step S173 is completed, in step S175, the basic input/output system 11 selects the next pin to be configured according to the control pin interval data. For example, when the control pin start data indication is configured from the third pin and the control pin interval data indication is separated by 2 pins, the basic input/output system 11 selects the first The 3 pins start to be configured, and the 5th and 7th pins are successively arranged at intervals of 2, and so on, until the sequence number of the pin reaches the total number of pins set in the external file, that is, the external The total number of pins set in the file is used as the stop condition. The present invention does not limit the pin parameter values actually indicated by the control pin start data and the control pin interval data.

In the conventional general-purpose input/output port configuration method, the configuration of each pin has been written into the program that executes the configuration method in advance, which means that for various platforms (chips), the conventional general-purpose input/output port The configuration method must design multiple configuration programs to respond to the various platforms separately. In contrast, one or more embodiments of the present invention design a universal master program to perform the process of chip identification and pin configuration by separating the configuration program from the pin information that varies with different platforms, and integrate various chips. The structure information and its pin information are stored as external files, thereby reducing the storage space occupied by the configuration program in the computer device, and can efficiently switch between platforms of different specifications.

Please refer to FIG. 1, FIG. 2 and FIG. 6 together to explain a general-purpose input/output port configuration method according to another embodiment. FIG. 6 is a flowchart of the method according to this embodiment. In step S21 of FIG. 6, the basic input/output system 11 reads external files from the external file database 13.

In step S22, the basic input-output system 11 retrieves chip information from the chip 5. Among them, the chip information may include bus data, device data, and function data. In this embodiment, the basic input/output system 11 can retrieve the chip information of the chip 5 through the main program 113 and store it in the memory 215, and then read the chip information in the memory 215 in step S23, based on The obtained external file and chip information are used for the subsequent chip identification process, including steps S24-S26.

In step S24, the basic input/output system 11 searches and selects one of multiple device ID codes in the external file. In step S25, the basic input/output system 11 determines whether the selected device identity code data matches the chip information. Further, the basic input/output system 11 determines whether the device ID code data and the device data in the chip information are the same. When the judgment result is no, as shown in step S26, the basic input/output system 11 will judge whether the device ID code data is the last device ID code data in the external file that has not been selected. If not, the basic input/output system 11 will perform the aforementioned steps S24 and S25 again, and select another device ID code data to compare with the chip information; if it is, it means that there is no data in the external file that meets the specifications of the chip 5, so the end Configuration process.

When the basic input/output system 11 determines in step S25 that the selected device ID code data matches the chip information, as shown in steps S27 and S28, the basic input/output system 11 defines the attributes of the chip 5 and loads the corresponding pins of the chip 5 Bit information. Further, the basic input/output system 11 loads the pin information corresponding to the chip 5 into the register 213 to set the potential of each pin of the universal input/output port 211 through the register 213. The method of setting the pin position is as described in the embodiment of FIG.

With the above structure, the universal input and output port configuration method and system disclosed in this case design a universal main program and external file format, where the external file contains structural information of various platforms (chips) and corresponding universal input and output For port configuration information, the universal main program is executed to read external files and chip information, to determine the attributes of the chip connected to the universal input and output port to be controlled, and then to configure the universal input and output port. By storing the universal main program and external files in a computer device and an external database such as a cloud device, the method and system for configuring universal input and output ports disclosed in this case do not need to store the complete control code corresponding to multiple platforms in In the computer device, the occupied storage space is reduced, and it can be efficiently switched between platforms with different specifications. In addition, when a new standard platform is released in the future, the general input and output port configuration method and system disclosed in this case only need to update the contents of the external file, without re-developing the overall control program of the general input and output port, to reach the development process Simplification.
