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. 115
