Abstract

Interrupt process and trigger is to some extent the main way computer system interact with external device or system. Device with operating system could complete done this by system core and drivers, but soc or embed system running program directly need to handle the things themself. For the fact that rapid response and random interrupt occasion, it could not ensure completely the program for function data unmodified between before and after interrupt. Thus interrupt spot protection as operating system interrupt function but running directly in soc system using only necessary program is important for the some environment. This article propose a way to realize interrupt spot environment protection in soc or embed system, divide memory to two subs to realize interrupt and program data both integrate among interrupt process. Finally test by experiment and conclude result interrupt protection use 8% extra processor time and realize data correctness as expected.
