Ticket Name: Linux/TDA2: Why CPU utilization can't be improved anymore

Query Text:
Part Number: TDA2 Tool/software: Linux i am using SDK_VISION_03_04_00_00 i run my algorithm on a15 i test CPU usage rate by top . can CPU usage rate increase？ and make my algorithm fast. what is the nic 45% idle irq mean? thanks ! shuai

Responses:
Hi Shuai, The CPU utilization depends on previous links connected to the A-15 link. If the link connected to the A-15 link sends data periodically and the A15 link is able to process the data before the next burst of data, then the CPU load will be limited. If a while loop is run in the link you will notice the A15 load also spike to 100%. Regards Shravan

Hi Shravan i run the program in the main with out link. (sample_app\src\hlos\chains_common\chains_main.c) i do not call usecase. Regards shuai

Hi Shuai, In an idle state the sample-app.out application runs nothing and thus the A15 load is almost 0% due to the application. You need to check what modifications you've made (most likely you're polling on the status of some content) which is causing the increased load. Regards Shravan
