| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Microprocessors (CPU on a Chip) (microprocessors_cpu_on_a_chip) | historical_predecessor | 70% | expert_inference | Microprocessors and single-chip integration are immediate historical context for SoC designs, but the 1974 watch SoC integrated timing and display functions rather than a general CPU system. |
|
| CMOS Logic (cmos_logic) | required | 82% | expert_inference | The first true SoC cited for this scope was an Intel 5810 CMOS chip, so CMOS logic is a component dependency for the chosen anchor. |
