Why HPSC Is a Big Deal for Space Exploration

Is this the one with the SiFive x280 in it?

> 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?

Intel is also interested in this market. https://www.intel.com/content/www/us/en/content-details/9234...

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
