TDA2SX: Data logging on TDA...best/most developed method?

_Lina

Part Number: TDA2SX
Other Parts Discussed in Thread: TDA2

Hi Team,

Regarding algorithm validation via data logging on TDA2 series of parts, which is the recommended/typical interface and why? (i.e. ethernet, straight to SD card, USB to PC)?

Do we have any software tools on the PC side already developed to receive video data? I'm aware of example Ethernet usecase which sends one frame at a time, but wondering if we have something more advanced.

Hi Lina,

I have forwarded your question to VisionSDK experts to comment.

Hello Lina,

In vision SDK we have 'null' link which can be used for data logging. Currently it supports Ethernet, SD card and memory write. The choice of interface depends on throughput requirement of use-case. Ethernet supports higher bandwidth (upto 600Mbps TCP/IP) where as SD(~10Mbps) and memory are limited.

If you want to log only few frames you can use SD card but for large video Ethernet is recommended.

You can use opensource tools like ffmpeg, yuvplayer etc. for analyzing the post processed data.

Hi Prasad,

Thanks for the information. What about USB? Have you seen that implementation with a PC?

Best,

Hello Lina,

USB/PCIE are not supported with current implementation of null link.
