- Correct me if I am wrong. For the last 20 years, we have 4-bit
- microprocessor, CISC, cache, RISC, superscalar, superpipeline,
- etc. Have we reached a point of diminishing return in uniprocessor
- design? Could we still get a speedup of "X" every "N" years like
- before? The above evolutions are just experiences we learnt in
- building big machines like the IBM 390. I think it is a time for
- MIMD and a change of serial programming style.
