Design Principles

"Embrace variability through parallel processing for enhanced system resilience and efficiency."

In high-volume manufacturing, especially for microelectronics, variations in component performance are inevitable. Understanding how to design systems that are tolerant to these variations, rather than trying to eliminate them entirely, can lead to significant cost savings and improved product reliability.

What This Means for Your Design

Even if some parts made in a factory aren't perfect, using many processors working together can help the whole system run smoothly by working around the imperfections.
