Embodiment Construction

[0021] Please refer to FIG. 1 . FIG. 1 is a flow chart showing the implementation of the method disclosed in the present invention. Firstly, relevant data of the microprocessor coupled to the bridge chip is obtained (step S10 ). Then, according to the relevant data, the bit configuration of the system bus connected to the bridge chip is determined (step S12). The aforementioned related data is obtained by detecting the microprocessor connected to the bridge chip.

[0022] The system bus can be a transfer bus for connecting peripheral components to connect the central processing unit and the bridge chip. The bit configuration includes a bus number field, a device number field, and a function number field. Therefore determine the bit configuration of the system bus connected to the bridge chip, that is, specify the number of bits in the bus number field, device number field, and function number field.

[0023] The specified number of bits can be implemented by the bridge chip...

Abstract

A method for dynamically determining bit configuration for a host bridge. The method first obtains information of peripheral components coupled to the host bridge. Next, the method dynamically determines a bit configuration of a processor system bus connecting to the host bridge according to the obtained information.

Description

technical field [0001] The present invention relates to a method for setting bus bit configuration, in particular to a method for dynamically determining the bit configuration of a bridge chip. Background technique [0002] In computer-related system architecture, a peripheral component interconnect express bus (PCI express bus) is used to connect a microprocessor (microprocessor) and attached devices. In current microprocessors and attached devices, the system bus must be able to support higher bandwidth to meet the requirements of frequency and voltage. Since the peripheral device connection transfer bus can support the frequency and voltage requirements, the peripheral device connection transfer bus has been selected as the standard specification of the system. In the foreseeable future, the peripheral component connection transfer bus will play an important role in computer system-related applications. [0003] The peripheral component connection transfer bus utilizes ...
