#3Fun times, can't wait to have these in the Cortex M line. Of course the chips start to look more and more like the Pentium line of old.

So, Helium is similar to Neon, but optimized for simpler CPUs with fewer gates.

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.

#8The current dsp instructions are pretty limited, interested in seeing these!

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]

ARM has done an incredible job legitimizing RISC-V.
