Problems solved by technology

[0003] The concept of network computer appeared in the 1990s. At that time, the starting point was to cut down some devices in personal computers (such as hard disks, optical drives, floppy disks, etc.) as much as possible to reduce the cost of computers. At that time, the cost of personal computers was relatively high. This kind of thinking has a certain meaning, but with the increasing performance-price ratio of PCs, the price of PCs is already very low today. From the perspective of cost reduction, the advantages of network computers are not obvious.

Embodiment Construction

[0029] figure 1 Among them, GODSON-1 (Godson-1) 1 is the central processing unit of the whole system, responsible for the operation of the program, and it is the core of the system. It communicates with Northbridge 2 through its own data line, and the data to be processed and processed data are sent to the memory through Northbridge 2. North Bridge 2 is responsible for providing memory control logic, and is responsible for providing CPU reset timing, and another important function is as the master controller of PCI devices. The local bus (local bus) on the north bridge 2 is mounted with the BIOS 3 chip of the entire network computer. At the initial stage of system startup, the BIOS 3 is responsible for the initialization of the entire system. The PCI bus (BUS) on the north bridge 2 is also connected with the south bridge 4 and other PCI devices (such as graphics cards and network cards, etc.), and the north bridge 2 is responsible for functions such as arbitration on the PCI ...

Abstract

The invention relates to the main board system and the reset method of the networked computers using a kind of 'Longxin'-1 CPU. The system includes the 'Longxin'-1 CPU, the north bridge, south bridge and the basic input/output system. The reset method is as follows. Starting the reset button through the reset generation circuit generates the reset signal sent to the south bridge, making the south bridge be reset. The new reset signal generated by the south bridge is sent to the north bridge, making the north bridge be reset. With the north bridge being reset, the reset signal generated is sent to the 'Longxin'-1 CPU, making the 'Longxin'-1 CPU be reset. The invention not only makes use of the technique adequately but also adopts many new technique and thought creatively. The system possesses high practicability.

Description

technical field [0001] The invention relates to a network computer, in particular to a network computer motherboard system and a reset method of a Godson-1 CPU. technical background [0002] Network computer is an important application branch of computer technology development. With the increasing development of computer network technology, it has the advantages of high security, easy management, simple software upgrade and maintenance, and low cost. The application prospects of e-government, e-commerce, e-agriculture and other aspects have been paid more and more attention by people. [0003] The concept of network computer appeared in the 1990s. At that time, the starting point was to cut down some devices in personal computers (such as hard disks, optical drives, floppy disks, etc.) as much as possible to reduce the cost of computers.
