Embodiment Construction

[0045] A first embodiment of a single-channel master control device with dual CPUs of the present invention, as shown in FIG. 3 , includes a master CPU, a slave CPU, a mailbox device, and a 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.

[0046] Among them, the mailbox device includes: dual-port RAM, or ordinary memory plus logic control device, or ordinary memory plus I / O controller and other devices capable of generating interrupt signals. The implementation process of interrupt-level fast communication specifically includes: when the slave CPU has emergency information...

Abstract

The disclosed one-way primary control device with dual CPU comprises: a primary CPU connected the secondary CPU by e-mail and high-speed channel, an e-mail device to provide interrupt-level fast communication, and a high-speed channel to transfer information between dual CPU. This invention realizes large-capacity communication and fast process for emergent affairs.

Description

technical field [0001] The invention relates to communication equipment management technology, in particular to a main control equipment with dual CPUs (Central Processing Unit, central processing unit) and an implementation method. Background technique [0002] In the prior art, the circuit structure of one CPU is usually adopted, but the processing speed of one CPU is limited after all. In some application environments that require high processing speed, the processing speed can be increased by working together with two or more CPUs. In the existing dual-CPU system, a single channel interconnection is used between the master and slave CPUs, such as: shared memory, dual-port RAM (Random-Access Memory, random access memory), I / O (Input / Output, input / output) port, serial port, I2C (Inter-Integrated Circuit, internal integrated circuit bus) and other methods. [0003] An example of implementing a single channel interconnection in the way of shared memory is shown in Figure 1:...
