Embodiment Construction

[0010] figure 2 is a block diagram of a computer system 200 according to an embodiment of the present invention. The computer system 200 includes a CPU 110 , a system chipset 120 and a hierarchical USB I / O system 150 . The hierarchical USB I / O system 150 includes an I / O control chip 140 and a USB connection port 130 . The system chipset 120 includes a north bridge chip 122 and a south bridge chip 124 . figure 2 and figure 1 Similarly, except that the I / O control chip 140 is connected to the south bridge chip, and the USB port 130 is connected to the I / O control chip 140 instead of the south bridge chip 124 . exist figure 2 and figure 1 Components marked with the same number have the same function, so they will not be described here. In this embodiment, the input / output control chip 140 can be a super I / O (super I / O) chip, such as the super I / O chip of model VT-1211, which is used to control various computer peripheral devices , such as floppy drives and keyboards, mo...

Abstract

A straum type of USB I / O system is prepared as using system chip set to control data transmission, setting I / O control chip between system chip set and USB connection port to let system chip set control data transmission of USB connection port through I / O control chip, enabling to make USB connection port use less system chip pins since transmission speed between I / O control chip and system chip set is greater than that of USB connection port.

Description

technical field [0001] The present invention relates to a computer system; especially a computer system with a hierarchical USB input / output system. Background technique [0002] The Universal Serial Bus (USB) integrates various existing peripheral interfaces of the computer system, so that all computer peripheral products use the same interface, so users will no longer be compatible due to different interfaces. sexual distress. In the past, if you want to add peripheral devices to the computer system, such as digital cameras, printers, monitors, modems, keyboards, mice and other peripheral devices, you must perform very complicated installation procedures, but the USB plug and play (plug and play) and play) ability to make these problems completely disappear. Therefore, in today's computer systems, multiple groups of USB connection ports (ports) are built in to facilitate users to connect and use various peripheral devices. [0003] figure 1 is a block diagram of a conv...
