Image capture using AM4376

Other Parts Discussed in Thread: AM4376

Hi

We are working on an architecture design for battery operated car camera product.

We need to reduce all over system power consumption with different power mode like standby mode or deep sleep mode.

Can DMA take camera images and transfer it to DDR in sleep mode/deep sleep mode without CPU’s involvement in AM4376?

Thanks

    What OS are you targeting?

    In deep sleep mode, DMA and CSI controllers are usually turned off as well. You may be able to keep them on but the overall consumption will not be as good as what you might expect from a "deep sleep". Also deep-sleep generally means the DDR is in self-refresh so that you can shut down the DDR controller, in your case you will need this one on as well.

    Also are you targeting any OS? In Android for example, DMA cannot operate camera alone, there usually are some reconfiguration steps involved where the CPU has to work.
