Meantime, in the royalty-free side, RISCV's work on V extension continues: https://www.embecosm.com/2018/09/09/supporting-the-risc-v-ve...

Hard to tell, with ARM's incredibly vague language, whether MVE is a vector extension, or just a packed SIMD extension.

Added: I'm sufficiently insulted by how tedious they've made it to download related documents, that I'll leave it to somebody else to care enough. [0]

I wonder what level of concern RISCV raises internally at ARM. Are they panicked, or just adjusting strategy in a more routine way?

It seems the moves from Western Digital would be concerning to them.

Though I suppose on the other side, there's not yet any credible/volume RISCV general purpose CPUs yet (just MCUs), so maybe they aren't yet scrambling.

Given their public reactions, I imagine they see it as an existential threat.

ARM has done an incredible job legitimizing RISC-V.
