IBM had the opportunity of being the royalty-free ISA that RISC-V is. Or even release the cores "IP". They squandered it.

- smarx007 5y ago"squandered [..] the opportunity of being the royalty-free ISA" Last time I checked, IBM was a business. I don't think losing an "opportunity" to give away the ISA for free sounds like a loss to them.

- classichasclass 5y agoThe ISA is open and royalty free. There are at least three open cores, all IBM funded or designed: https://github.com/antonblanchard/microwatt https://github.com/antonblanchard/microwatt https://github.com/openpower-cores/a2o https://github.com/openpower-cores/a2o https://github.com/openpower-cores/a2i https://github.com/openpower-cores/a2i The last two are older but they work. Microwatt is developing by leaps and bounds.
- goodpoint 5y agoI'm aware. The problem is that the ecosystem has been opened up too late, while the RISC-V ship has sailed and also missing the opportunity to disrupt datacenters and phones.
