Method for making centralized control processing by utilizing CPU on system board

Abstract

The invention is a method for using CPU on system board to carry on centralized control process, it at least includes: (1) the CPU on the system control board provides bus to each single board, the system control board also sets bit line and chip selecting signal line for each single board; (2) allocates a address to each slot board; (3) the CPU on the system control board carries on intensive control process to all single boards through the CPU bus, each combinations of bit lines and chip selecting signal line; the single board requests control process through sending out interrupt or warning signal to CPU.

Description

technical field [0001] The invention relates to a control processing method in a communication device, specifically, a method for centralized control processing using a CPU on a system board, and belongs to the technical field of communication control and communication processing in digital information transmission. Background technique [0002] At present, in the entire communication product, the control and management of the entire equipment system is to use the network management, command line, point-to-point (PTP, point to point) method to complete the distribution of configuration, query alarm performance, and perform multiplex section switching through the main control software. And so on a series of functions. The realization of these functions not only requires protocol communication between the computer terminal and the main CPU of the system control board, but also requires the system control board to send corresponding control information to each board and be able...

AI Technical Summary

Problems solved by technology

[0007] The shortcoming of this prior art is: (1) existing control and processing technology belong to distributed control

Not only the cost of the chip device has increased significantly, but also the area of ​​each single board is larger and the circuit layout is complicated, resulting in a larger volume of the entire device, higher manufacturing costs and lower operating reliability.

(2) Because each board has a different priority of the interrupt level of the processing task, the processing of alarm information, command configuration, etc. of each board may not be responded to or completed in time

(3) There is a certain degree of unreliability in the method of completing communication through the mailbox. Once the mailbox is damaged, it will directly lead to communication failure; because the system control board will not be able to poll events such as interrupt requests and performance alarms.
