Embodiment Construction

[0030] In this embodiment, when the baseband chip generates an interrupt, it sends an interrupt flag to the co-processing chip through the data / address multiplexing bus (hereinafter referred to as the multiplexing bus), and notifies the co-processing chip to perform operations related to the interrupt. This embodiment provides a co-processing chip including at least two hardware stacks (hereinafter referred to as stacks), one of which is used to process data and addresses in normal mode, and the other stack is used to process data and addresses in interrupt mode. The normal mode in this embodiment is relative to the interrupt mode, that is, the working mode after no interrupt is generated or the interrupt ends.

[0031] The baseband chip can send an interrupt flag to the co-processing chip through the data multiplexing bus in the form of data, or send the interrupt flag to the co-processing chip in the form of an address through the data multiplexing bus, depending on the locat...

Abstract

A method for processing interruption includes generating interruption by base band chip and using complexing bus to send interruption start-up flag to coprocessing chip then sending interruption ended flag to said coprocessing chip by base band chip through said complexing bus when interruption treatment is finished. The system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the field of computer and electronic technology, in particular to an interrupt processing method and system. Background technique [0002] The current embedded system includes a baseband chip and a co-processing chip. The baseband chip has a general processing function, and the co-processing chip has a specific processing function. One of the main development directions of the embedded system is to realize support for more multimedia services, such as chords, ring tones, video and audio compression format (MP3) services, etc. In the prior art, the baseband chip often uses dedicated pins (pins) to send various information to the co-processing chip. One of the applications is that when the baseband chip generates an interrupt, it sends an interrupt signal to the co-processing chip through the pin. Embedded systems usually have higher requirements on chip size and power consumption, so pins become a limited and precious resource....
