Abstract

The invention discloses a method for estimating the property of an embedded type system, comprising the following steps: continuously collecting the time information of a function and the state information of a corresponding function in real time; and realizing the property estimation of the embedded type system in a way of collection result statistics. The invention also discloses a system for estimating the property of the embedded type system, comprising a collection unit, a statistic unit and an estimation unit, wherein the collection unit is used for continuously collecting the time information of the function and the state information of the corresponding function in real time and sending a collection result to the statistic unit; the statistic unit is used for carrying out the statistics on the collection result and sending a statistic result to the estimation unit; and the estimation unit is used for realizing the property estimation of the embedded type system according to the statistic result. The method and the system can precisely estimate the property of the embedded type system.

Description

technical field

[0001] The invention relates to the field of embedded systems, in particular to a method and system for evaluating the performance of an embedded system. Background technique

[0002] In existing embedded systems, the processor (CPU) occupancy rate when the system is running is an important index to measure the performance of the system. The usual measurement method is to start an idle task with the lowest priority when the system is running. The running time slice of the idle task, and then subtract the running time slice of the idle task from the total running time to get the running time of all other processes in the system. In this way, the CPU usage of the embedded system can be calculated Rate. For example, the Chinese patent publication number is CN02157690, and the title of the invention is "a method for detecting CPU usage in a multi-task real-time operating system." The running time slice of each process. It takes the process as the basic statist...
