Reducing the register count is not a "RISC" move. It probably makes sense for the target die size of a given product, but it's definitely not something "RISC" related which was, at the time, about doing the exact opposite - increasing the register count relative to CISC CPUs. Similarly divide wasn't removed. It's still there. Instead a second extension was added that introduced multiply-only variants. Total complexity was increased, not reduced. |
