Part Number: TDA2E
Other Parts Discussed in Thread: TDA2

I have a camera AR0143 and I want to send its datas directly to the CPU.The camera's data flow has 12 data bits,one flame_valid bit , one line_valid bit and one sys_check bit.Whether the TDA2xx chip can support

this design?And can I find driver models to modify for this design?The follow is hardware design.

Yes, it looks fine.

One suggestion, if you use line valid as DE signal, it would be better.

The camera'data flow is RAW/Bayer.I find the capture Driver in the SDK dosen't support this kind data flow.Should I add an encode chip or modify the capture driver to convert the data flow?

Please note that processing Bayer images requires an ISP which is not available in TDA2E SoC. This is why the SDK does not support this format.

It is possible to modify the capture driver for 12b RAW format. But how will you consume the raw image sent by AR0143?

I want to modify the driver to convert RAW to RGB or YUV．if this way wil add CPU much burden?Can you recommend several ISP chips for TDA2xx?

I am thinking to choose software encoding or hardware encoding ,do you have saome advice?Thank you!

Yes, doing it in software would cause very high CPU load. I would recommend TDA2PX. This is a device is TDA2 family with internal ISP. It will allow you to reuse all your existing code from TDA2E.
