So recently, it has come to my attention that the Power ISA is quite large.

We should itemize its characteristics - just at least so I can get an 
idea of labor involved for future cost analysis...


  - How many instructions

  - What is the minimal viable subset of the ISA we must support

  - I hear the decoder is more complex - why?

  - How does complexity overall compare with RISCV
