Abstract

The invention discloses an electronic device, a network switch and an interrupt transmission and reception method. The electronic device includes a slave chip and a master chip. The slave chip is used for generating a plurality of data segments and at least one piece of interrupt information, and comprises an encoder. The encoder is configured to encode data segments and interrupt information to generate digital data. The interrupt information is located between the data segments. The master chip is coupled with the slave chip, is used for receiving digital data, and comprises a decoder and a control circuit. The decoder is configured to decode the digital data to obtain a data segment and interrupt information. The control circuit is coupled to the decoder and is used for processing interrupt information.

Description

technical field [0001] The present invention relates to interrupt handling, and more particularly to the transmission and reception of interrupts. Background technique [0002] figure 1 It is a functional block diagram of an existing electronic device. The electronic device 100 includes a master chip 110 and a plurality of slave chips 120 . The main chip 110 includes a plurality of interrupt pins 116 , a plurality of data pins 118 and a control pin 119 . Each slave chip 120 includes an interrupt pin 122 , a data pin 124 and a control pin 126 . The slave chip 120 is in charge of a part of the electronic device 100 and transmits data to the master chip 110 through the data pin 124 and the data pin 118 . The slave chip 120 generates an interrupt notification when detecting an interrupt event, and transmits the interrupt to the master chip 110 through the interrupt pin 122 and the interrupt pin 116 . The interruption event is, for example, data abnormality or circuit abnorm...
