Appendix C
MICROPROCESSOR OPERATING AND STRUCTURAL PARAMETERS
Progress in operating and structural parameters of microprocessors has
been rapid in recent years. The progress and future projections are shown in
the accompanying figures, C-l through C-4. These figures were prepared from
information drawn from trade journals, forecasting reports, and the direct
knowledge of committee members of developments in the field. It should be
clear that predictions beyond 10 years are hazardous, at best.
