Problems solved by technology

After all the chips on the board are running, any chip may become faulty during the working process and cannot provide the processing capability the chip should have. It cannot be restored to normal through pure software reset, which will lead to the failure of the entire real-time processing system. Performance degradation, even affecting the performance of the entire network

Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] figure 2 Shows the flow of a real-time chip dynamic loading method of the present invention, in image 3 In we can see the corresponding structure of the real-time operating system with dynamic loading function. It has a central processing unit and several chips with the same function, and each chip has no data processing capability when it is not powered on. Chip 1, chip 2, ..., chip n have m ports respectively, each port corresponds to a PCM time slot, and each PCM time slot is connected to a public telephone network PSTN user, so the system can simultaneously provide n× The function for m public telephone network PSTN users to access Ethernet.

[0018] Such as image 3 As shown, a firmware with loading function is set up, and the data processing function of each chip with the same function is stored in the...

Abstract

A real-time dynamic loading method for chips is disclosed. In a real-time operating system composed of CPU and several chips same function, a loadable firmware is used for storing the data processing function of the said chip. All ports of the chips are controlled for write-in and read-out in turn periodically by the CPU. When a chip is found in failure, the contents of the said firmware is loaded to the chip to make it be normal quickly. The corresponding operating system is also disclosed.

Description

technical field [0001] The invention relates to a chip loading method, in particular to a chip dynamic loading method in a real-time operating system. The invention also relates to a real-time operating system with dynamic loading function. Background technique [0002] A distributed integrated design is often used in computer systems and data communication systems. It integrates many structures with identical functions on the same single board, and these structures perform exactly the same functions. This structure is especially suitable for access servers for remote access of data communication. The access server is an access device for remote access. It is located at the interface between the public telephone network and the local area network that provides access services, and connects many dial-up users to the local area network. Users of the public telephone network can call into the access server through the E1 interface of the PCM trunk line. The access server will...
