Does that change with ARM? If you're licensing the ISA, or even bits of HDL, you're still fabbing your own stuff, right?
If it was the choice between pre-made RISCV and pre-made ARM, then the licensing could play into a cost difference between models, but otherwise they'd both be pre-fabbed, ready-to-use-products?
- panpanna 7y agoBut then why bother if you are just using someone elses pre-made macros with a fixed architecture (cpu + memories + peripherals + power & clock distribution)? At this stage, would it even be cheaper? I think there is some merit to risc-v but people pushing hard for it's use RIGHT NOW don't seem to understand the challenges of SoC design and manufacturing.
