Will,
Though SPE is just an optional feature of the Armv8.2-A extension, I am wondering whether CPUs are already out in the fields or some vendors are planning to make one of two in the near future.
Itaru.

Thank you Sudeep. I look forward to more N1 variants showing up in the market in 2020.

HiSilicon Kunpeng 920 (ARM64 server chip) has SPE feature and we are working on
this to enable it with more perf support:
