TDA4VM: Is there an SDK to implement In-Frame and Frame-to-Frame Redundancy?

Jewin Jeong

Part Number: TDA4VM

Hi,

When I look at the diagnostic information of VPAC, there is "In-Frame and Frame-to-Frame Redundancy", is it implemented in SW?

If so, is there an available SDK or API to implement this?

Best Regrads,

Where do you do find this?

I am not aware of anything similar in VPAC H/W.

Hi Gang Hua,

In the hardware and software diagnostics in the TDA4VM Safety Manual document, VPAC3 is labeled "In-Frame and Frame-to-Frame Redundancy".

OK, thanks!

Safety manual is under NDA and we cannot discuss its information on public forum.

In general, redundancy probably means H/W ECC.

OK, thanks.

Then I'm curious about the operation principle of the Frame-to-Frame technique. As far as I understand, if there is a large difference in pixel information by comparing the Nth Frame and the N+1th frame, it seems to be defined as a fault. Is my theory correct?
If so, is this Frame-to-Frame continuously being checked in real time?

I don't think VPAC checks on pixel values.

For information under NDA, you will have to go to private e2e.

Ok, Thanks.

Please tell me how to access private e2e.

I am not sure about the formal process.
Please contact your local TI support for details.
