Doubtless Computing is apparently the blogger's new startup.
He had previously co-founded the CPU startup VyperCore, which had been based around technology in his PhD thesis at the University of Bristol. The startup folded earlier this year.[1]
VyperCore's main selling point was that having garbage collection in hardware could run managed languages faster, and with less energy. Apparently they came as far as running code in FPGA. Except for the object-addressing hardware, it was based on a RISC-V core.
I wonder which assets (patents and other) that the new company has been able to get from the old.
Both companies were/are apparently targeting the data centre first... which I think is a bit bold, TBH. I follow RISC-V, and have seen maybe a dozen announcements of designs for wide-issue cores that on paper could have been competitive with AMD and Intel ... if only they would have got to be manufactured in a competitive process. But that is something that would require significant investment.
A pretty reasonable summary of things from an outside perspective - have my thumbs up ;)
(And a very good question, to be answered at a later stage.)
