This illustrates how a complex instruction format impacts performance.
I'm not sure how much simpler it could be? The propagation delays are intrinsic to the process.
Even 32-bit ARM isn't particularly easy to decode, and there are plenty of special cases there as well. 64-bit ARM is even more complex, like they tried to cram as many operations as they could in 32 bits of instruction.
Maybe MIPS is simpler to decode, but I remember seeing lots of odd gaps in the opcode map, and it's not really an example of high performance either.

@kens Off the wall question, i may have a working 8088 that has been stored in an air conditioned basement at my parents. I learned to program on this in the 90s. Is there a practical benefit of getting it running again?
