Description
The key applications:
– H.264/H.265 transcoding
– processing of many compressed video feeds from network IP cameras
– inferencing applications in low energy data centers
– designed for 19″ rack integration and open rack systems
– desktop use: flashing station for Nano, TX2 NX and Xavier NX
Each compute module slot has a local NVME SSD with up to 2 TB. Optionally we integrate the Transcend TS2TMTE662T2 (2 TByte industrial grade NVME SSD).
The JNX400 integrates a 5 port GbE switch which connects to each of the 4 compute modules.
On top we have integrated four 5Gbit communication channels:
1. 2x horizontal: USB 3.0
2. 2x vertical: 2 lane DSI to CSI-2 (full duplex bi-directional)
On the JNX400 there is a little drawing between slave 1 and 3. Here the hardware is done – but the challenge now is to develop software (drivers) for it.
Limited rev 1 samples are available now.
A second use case for this board could be a flashing station for Nano, TX2 NX or Xavier NX. Here the master slot would be populated by a Nano.
