The PDF linked in the article provides much more information on the technical details: https://www.nasa.gov/wp-content/uploads/2024/07/hpsc-white-p...

> The PIC64-HPSC series has a built-in 240 Gbps, 16-port TSN Ethernet switch with Remote Direct Memory Access (RDMA) that uses the RDMA over Converged Ethernet (RoCE) version 2 standard

It seems like this is what the article is referencing. However, the ethernet embedded CPUs have "GigE" or even 10/100 capability. Why the need for 240 Gbps with 16 GigE ports? Are the ports 10G fiber capable and they are just future-proofing or is there something I missed with the time-slicing and RDMA?

Looks like the press release is mixing up the chip level with some board or assembly. The MPUs in the family look like 10G by themselves, so maybe the board includes the switch and shared memory.

Intel is also interested in this market.

Is this the one with the SiFive x280 in it?

I've always felt bad for windriver; they do a lot of good work and there are clear benefits but because linux is free people keep moving away from their products. It's cool to see them doing more RISC-V stuff though
