Multi-Threading: Powering The Next-Generation Of Embedded SoCs

摘要

Designers everywhere face ever-increasing constraints on system cost and power consumption, while at the same time are required to add more performance and functionality to their designs. Some previous approaches have been to ramp up the clock speed of a processor, but this usually results in increased power consumption. Additionally, memory performance has not kept pace with processor technology (Figure 1), and this mismatch limits any significant gains in system performance. Consequently, the higher frequency approach is leading to diminishing returns.
