AM5728 performance - single A15 vs dual A15

Hi,

I have one question regarding the cortex-A15 core of AM5728.

My customer measured the two types performances with AM5728. One is A15 single core. And other one is A15 dual core.

According to the measurement results, dual core performance is lower than single core performance. Because, when AM5728 runs with dual core, main core generates the interrupt to sub core frequently. So dual core performance is lower than single core working.

Do you know why this situation is happenning? OS is Windows embedded compact.

Please advise me.

I appreciate your quick reply.

Best regards,

Michi

 

  • Hi,

    TI does not support Windows CE. This question should be directed to Adeneo Embedded, who are the 3-rd party providing this product.

    I have AM572x EVM.
    Can I measure AM572x sigle core performance by using this evm?
    Please advise me.

    Hi,

    I would like AM5728 to work as single core device, not dual core on linux SDK.

    For single core action,  to remove the check of Symmetric Multi-Processing is needed, I think.

    Is my understanding right? or is other action needed?

    Please advise me.

    Best regards,

    Michi

    Hi,

    This should be enough to build your kernel to work with only one A15.
