摘要

65nm多核Cell宽带引擎贸易(Cell/B.E.)*处理器的噪声特性使用高度可配置的工作负载和选择性刺激相同的核心来研究整个芯片的噪声分布。在配电系统中，芯片/封装谐振对片上电源噪声的传播速度和衰减有影响。对这一现象提出了假设。

Distributed On-chip Power Supply Noise Characterization of the Cell Broadband Engine

Noise characterization of the 65 nm multicore Cell Broadband Enginetrade (Cell/B.E.)* processor was performed using highly configurable workloads and selective stimulation of identical cores to study noise distribution throughout the chip. On-chip power supply noise propagation velocity and attenuation were found to be influenced by chip/package resonance in the power distribution system. Hypothesis for this phenomenon is proposed.
