I thought it was pretty obvious. They didn't control the ARM ISA and ARM Ltd designs had caught up to + surpassed XScale innovations (superscalar, Out-of-order pipelining, MIPS/w, etc). So instead of further innovating they decided to launch a competitor of their own ISA.
- KerrAvon 1y agoIntel at the time was clear about it: they wanted to concentrate fully on x86. They thought they could do everything with x86; hadn’t they already won against their RISC competitors by pushing billions into x86? Why would ARM be any different? Shortsighted, in hindsight, but you can see how they got there.
