Abstract

This application discloses a multi-node master-slave network system and its interrupt processing method. The multi-node master-slave network includes a network controller node and a plurality of network terminal nodes. The method includes: hardware writes the running state and counts When counting reaches the integral multiple of response frequency, the hardware reports message interruption to the software; after the hardware writes the running state, it is written into the message completion information queue, and the message completion information queue block is an independent cache area in the internal memory, and the message The completion information queue block is used to store the execution result of the message; the software responds to the message interruption; the software reads the message completion information queue block.

Description

technical field [0001] The present application relates to the field of multi-node communication systems, in particular to a multi-node master-slave network system and an interrupt processing method thereof. Background technique [0002] Hardware interrupt is one of the key links in the interaction process between software and hardware, and it is also the only way for hardware to actively initiate interaction. The message interrupt is a kind of hardware interrupt, which is used for the hardware to transmit the signal of the completion of the current round of execution and the execution result to the software. [0003] The FC-AE-1553 network is a high-bandwidth, low-latency, and highly reliable optical fiber communication bus protocol. Its protocol is formulated by the American National Standards Institute (ANSI) and defines the MIL-STD-1553B protocol to Fiber Channel (FC, FiberChannel) high-level protocol mapping, which provides protocol support for the development of optica...
