Bertl / se6astian - do you remember when a JP4 was first seen with the elpher hardware? (or any prior art on compressed bayer?)

*elphel
10:43
Bertl
nope, why?
10:44
danieel
trolling from a company who thinks invented the digital camera

should be easy to find such dates in the elphel wiki history
11:00
danieel
says 2010, so better to rely on cineform raw, that dates back to 2006
12:04
Bertl
off for now ... bbl

Hello Bertl_oO
16:12
ArunM
he checks logs, just droping link for the sensor emulator design document
16:12
ArunM
it has no specific format and casually explains the implemntation

16:14
ArunM
I've already started coding to test few things during designing
16:15
ArunM
but i'll wait for your review b4 going further

ArunM: looks good (just briefly checked it right now) here some points which need to be considered
18:35
ArunM
listening :-)
18:35
Bertl_oO
- the LVDS channels are not synchronized, they have a delay
18:35
Bertl_oO
i.e. they seem to be synchronized to the clock, but they all have a specific offset
18:35
Bertl_oO
(this is most likely to reduce the switching effects)
18:36
Bertl_oO
- some registers seem to have 'read only' bits and some registers are not well documented
18:37
Bertl_oO
so it would be good to have some masking mechanism there
18:38
Bertl_oO
- the clocks have to be in a specific relation to eachother
18:38
Bertl_oO
more detail on that later
18:39
ArunM
didn't found any specific information about it in the datasheet itself any other place to look?
18:39
ArunM
about clocks
18:39
Bertl_oO
there is some information in the datasheet but it is strangley worded
18:40
ArunM
yes i found it like that too ;-)
18:40
ArunM
okay I'll take care of the rest
18:41
Bertl_oO
great!
18:41
Bertl_oO
it might be cool to consider some kind of cosimulation and verification
18:42
Bertl_oO
i.e. at some point have the sensor simulation running side by side with a real sensor and check where we hit differences
18:45
ArunM
cool indeed but how is it possible?
18:45
ArunM
you are going to do that right!! i can only write test benches from here
18:46
Bertl_oO
well, if we can fit the simulation into the zynq together with the normal image pipeline, we just need to write a little HDL to compare the output
18:46
Bertl_oO
of course, this will only work for test image data
18:47
ArunM
nice, this project got more interesting
