Ticket Name: 8CH 720P capture on TDA2

Query Text:
Other Parts Discussed in Thread: TDA2 Hi all, I want to capture 8CH 720P with YUV422 8bit discrete sync mode on TDA2. My scenario is 4CH for 3D AVM, 2CH for side view, 1CH for front camera and 1CH for rear camera. It should be no problem when run in different situation. Otherwise, the above scenario happens simultaneously. I think the ddr bandwith should be the limitation. Could you please help to comment more about it? Thanks in advance. B.R. OC

Hi, Your question has been forwarded to an expert. Best regards Lucy

Hi Lucy, Any update? B.R. OC

Hi, Just sent a reminder. Best regards Lucy

OC, Sorry for late reply. I think this is doable with VIP1 and VIP2 as far as its 8bit YUV (Port B on each slice supports only 8 bit). DDR bw would also depend upon how your algorithms are operating, you can configure bootloader in dual emif interleaved mode to get maximum DDR banwidth if you want to run all this simultaneously. But when its not all simultaneously, I don't see a problem.

Please note that if you are using discrete syncs, 2 pins for each ports are available. and if you are using embedded sync, sync codes must be in bt656 format. BT1120 codes over 8bit interface is not supported. Rgds, brijesh

Hi Yogesh, Thanks so much for your input. It's clear to me. B.R. OC
