Embodiment Construction

[0036] A first embodiment of a single-channel master control device with dual CPUs in the present invention, as image 3 As shown, including main CPU, slave CPU, mailbox device and high-speed channel management device. Among them, the master CPU and the slave CPU are interconnected through the high-speed channel provided by the mailbox device and the high-speed channel management device. The mailbox device provides interrupt-level fast communication for emergency information between the master and slave CPUs. High-throughput information exchange, such as: transmitting analysis messages, query information and status information, etc.

[0037]Among them, the mailbox device includes: dual-port RAM (Random-Access Memory, random access memory), or ordinary memory plus logic control device, or ordinary memory plus I / O (Input / Output, input / output) controller, etc. can generate interrupt signal device. The implementation process of interrupt-level fast communication specifically inc...

Abstract

The disclosed one-way primary control device with dual CPU comprises: a primary CPU, a secondary CPU, and a business process module controlled by last CPU to form a visual board with CPU. It also discloses a two-way primary device, which includes: a primary CPU of the main primary device connected wit the primary CPU of standby device, a secondary CPU of the main primary device connected wit the secondary CPU of standby device, and a business process module connected by the secondary CPU of primary device. This invention can prevent business interruption or system re-startup.

Description

technical field [0001] The present invention relates to communication device management technology, in particular to a master control device with dual CPUs (Central Processing Unit, central processing unit). Background technique [0002] Communication equipment usually includes a main control device and a line card board, wherein the line card board is a single board used for business processing, and includes a business processing module on it; the main control device is used for management and routing calculation of the business transmitted by the line card board . In some special applications, customers want to obtain higher port density and reduce costs. In order to meet this requirement, the main control device originally only used for management and routing calculation will also undertake some business processing tasks, that is, integrate the business processing module into the main control device, and use the original CPU system of the main control device to directly ...
