Problems solved by technology

Although this patent uses the timing program of the instant timer to allow the system to temporarily suspend and restart automatically to save labor time costs, it cannot be tested for the interruption function of the instant timer
[0005] This shows that the above-mentioned existing real-time timer interrupt request test method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently
In order to solve the problems existing in the interrupt request test method of the real-time timer, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method for general test methods. To solve the above problems, this is obviously a problem that the relevant industry is eager to solve

Abstract

A method for detecting demand timer interruption request under Linux or Window operation system includes energizing interruption mark of the first state working storage on demand timer to issue an interruption request to demand timer for triggering up interruption of demand timer, fetching mark value of the second state working storage on demand time and judging whether interruption request function of demand timer is normal or not according to said mark value.

Description

technical field [0001] The invention relates to an interrupt function testing method, in particular to a real-time timer interrupt request detection method under a Linux or Windows operating system. Background technique [0002] The real-time timer (RTC) is an application-specific integrated circuit that can provide functions such as calendar / timer and data storage. It is often used in timer signal sources and parameter setting storage circuits of various computer systems. Low and small size, etc., especially used in various embedded systems to record the time of event occurrence and related information, it has the characteristics of generating timed interrupts or starting the system. [0003] In the past, in the interrupt request test method of the real-time timer, by changing the interrupt vector table, when the interrupt is triggered, enter a new interrupt handler to count, and then judge whether the interrupt function is normal, but this method needs to mask Some other ...
