RISC-V argues the exact opposite :)
- twoodfin 9y agoWhat parts of RISC-V did you have in mind?
- dom0 9y agoThe whole idea of building an ecosystem of an open ISA with open implementations, where the ISA can be extended for specific applications. See e.g. https://riscv.org/wp-content/uploads/2016/12/Tue1100-RISC-V-Workshop-RoHC-ASIP-Accelerator-Cox-Synopsys.pdf https://riscv.org/wp-content/uploads/2016/12/Tue1100-RISC-V-... but it was also a salient point in the Patterson talk that was on the front page a few days ago.
