Problems solved by technology

[0004] In addition, embedded software interrupt performance evaluation is also a major difficulty
The conventional method of interrupt performance index measurement is to use soft interrupt simulation. However, this method cannot fully express the correct process of interrupt and requires external analog interrupt support.

Abstract

The invention discloses an embedded software performance evaluating hardware auxiliary test device, which is characterized by comprising a circuit board, wherein a control device and a plurality of communication ports are arranged on the circuit board, the communication ports are connected with a tested software operation hardware platform and a test system, and the test system is arranged on a PC (personnel computer). The invention also provides an embedded software performance evaluating hardware auxiliary test method, which comprises the following steps including 1, time measurement; 2, interrupt response measurement. The test device and the test method have the advantages that the burden of a tested system cannot be increased, the timing work can be also completed at high precision, and the external interrupt triggering can be simulated for data storage, processing and transmission.

Description

technical field [0001] The invention belongs to the field of software transmission protocols, and in particular relates to an embedded software performance evaluation hardware-assisted testing device and method. Background technique [0002] Software performance testing often uses time indicators, which are represented by absolute time intervals—the time difference between the start time and the end time. The usual measurement method is: insert the timing start sign before the first statement of the tested code, insert the timing termination sign after the last statement of the tested code, and take the time interval after the timing is terminated. Another test method is the number of executions per unit time, put the code under test in a loop body, and compare performance through multiple loop timings. The second method improves measurement accuracy by performing it for a long time. But no matter which method is used, the means of time measurement is very important. [0...
