It's a good sign that NVIDIA and Qualcomm are both integrating RISC-V for embedded controllers on their chipsets. This means that there will be experience and maybe R&D going into RISC-V cores at these two massive vendors of embedded and mobile CPUs. It is not inconceivable that RISC-V could... cross-contaminate to their high-performance application processor business.
- pjmlp 9y agoYeah, but will they give it back in some form? The examples of contributions from big players using BSD like licenses, specially in the embedded space, proves otherwise.
- imtringued 9y agoWhy does that matter? The only thing they need to do is correctly implement the RISC-V ISA instead of a proprietary ISA.
- pjmlp 9y agoBecause you will get into the scenario of commercial vendors basing their ISAs on RISC-V ISA with extensions not made available to the community. Thus making the base RISC-V ISA kind of useless for software that one might actually care about.
- microcolonel 9y agoVendors benefit from standardization when it comes to the ISA, especially in the commodity/interchangeable market. Qualcomm is currently competing with other vendors to run the same software (Android or Windows). If they make ISA extensions which are not likely to be used by that software, then they're probably wasting their time, or those extensions were not that useful for the general community to begin with. Useful ISA extensions are likely to remain royalty free at least, if not standardized at the level of the foundation; but if they don't, it's not the end of the world.
- pjmlp 9y agoExcept that is exactly what happens on ARM, for example.
- microcolonel 9y agoWhat proprietary ARM extension are you just dying to have?
- pjmlp 9y agoPersonally I don't care about RISC V's future, was just making the point things might not turn out as the comunity hopes for. To reply to your question, as a developer I don't care about ARM vendor specific features, because Android hides them for me. However as a consumer, they do impact updates.
