Problems solved by technology

However, every time interrupt nesting is performed, technicians are required to manually rewrite the corresponding code to save the contents of the relevant registers and restore the original working state, which is obviously time-consuming and laborious, which is not conducive to improving efficiency

Abstract

The invention discloses an ARM interrupt processing method. The ARM interrupt processing method comprises the steps of calling a package program code written based on a compilation language in advance if a first interrupt event is triggered, and performing corresponding processing by the package program code; calling an interrupt processing function written based on a C language in advance when an ARM processor is in a system mode state, executing an interrupt service program corresponding to the first interrupt event by employing the interrupt processing function, and closing shielding on interrupt during execution process of the interrupt service program; calling the package program code again to achieve interrupt nesting if a second interrupt event is triggered during the execution process of the interrupt service program corresponding to the first interrupt event. By the ARM interrupt processing method, labor cost and time cost which are required during the process of achieving ARM interrupt nesting can be substantially reduced. Moreover, the invention also discloses an ARM interrupt processing system.

Description

technical field [0001] The invention relates to the technical field of interrupts, in particular to an ARM interrupt processing method and system. Background technique [0002] Currently, ARM processor cores are used more and more widely. In the mobile device market, ARM processors have a market share of more than 90%. In the server market, ARM processors are expected to become mainstream. [0003] When an ARM processor processes an interrupt event, it often needs to perform nested processing on multiple interrupt events. However, every time interrupt nesting is performed, technicians are required to manually rewrite the corresponding code to save the contents of the relevant registers and restore the original working state, which is obviously time-consuming and laborious, and is not conducive to improving efficiency. [0004] From the above, it can be seen that how to reduce the labor cost and time cost required in the process of realizing ARM interrupt nesting is a probl...
