Hmmm... not as interesting as those VISC cores, we read about a few years back.
Anyway, good luck to them. They'll hardly have the RISC V market to themselves. It'd be interesting to know what manufacturing node they're using. I think they'll have to compete on price, because I imagine it'll take a few generations before they can close the power/performance gap with ARM.
The second is the F class, which can be thought of as an upgrade over the T class with additional support for redundant compute blocks and bus fabrics,
ECC memory and functionality to detect permanent faults.
...maybe for India's burgeoning space industry?
BTW, I have a suspicion the letters might stand for some Hindi words or names. If so, going with just the letters was probably a good call.
