Performance Increasingly Tied To I/O


Speeding up input and output is becoming a cornerstone for improving performance and lowering power in SoCs and ASICs, particularly as scaling processors and adding more cores produce diminishing returns. While processors of all types continue to improve, the rate of improvement is slowing at each new node. Obtaining the expected 30% to 50% boost in performance and lower power no longer can ... » read more
