Embodiment Construction

[0015] The present invention will be clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by persons of ordinary skill in the art without making creative efforts all belong to the protection scope of the present invention.

[0016] The system structure involved in the present invention is as figure 1 shown. The system is composed of a main control board 100 , a connector 200 and an interface board 300 , one or two main control boards 100 , multiple interface boards 300 , and one backplane 200 in one system. For simplicity, figure 1 Only one main control board 100 and one interface board 200 are drawn in the drawing. The main control board 100 and the interface board 300 are interconnected through the socket on the connector 200 .

[0017] An interrupt signal processing system, comprising a main control board 100, a connector 200 and an interface board 300, the main control board 100 is composed of a main control b...

Abstract

The invention relates to the field of communication and in particular to an interrupt signal processing system. According to the system disclosed by the invention, an interrupt processing module function is increased on CPLD between a master control board and an interface board, and the operation of interrupt state and control register between the master control board and the interface board is realized by utilizing two serial signal lines. All interrupt states of the interface board are reported to the CPLD of the master control board in a serial bus manner, the master control board processor only needs to execute once and perform bus access when interrupt happens, and the interrupt state is acquired from the CPLD of the master control board. Therefore, instruction per cycle allowing the processor to access peripherals is greatly reduced, load of the processor is reduced, and the interrupt response time is accelerated. The interrupt needs to be transferred between the interface board and the master control board by two signal lines only, and signal pins are greatly saved.

Description

technical field [0001] The invention relates to the communication field, in particular to an interrupt signal processing system. [0002] technical background [0003] On a distributed system communication device, there are multiple card slots on one device, and the slots are divided into main control slots, interface board slots, etc., and different slots are connected to each other through the backplane. to manage. Interrupts on the interface board usually need to be reported to the processor of the main control board for processing. A typical system is mainly composed of three parts: the main control board, the backplane, and the interface board. There are usually one or two main control boards and many interface boards. The usual practice is to place a CPLD on the interface board to handle peripheral interrupts. The types of interrupts include optical module plugging interrupts, temperature alarm interrupts, power-down alarm interrupts, and PHY internal interrupts. Aft...
