摘要:

根据SOC系统几种关键因素对总线的影响,本文提出总线性能分析模型用于分析增加流水线级数与提升系统性能之间的关系。利用分析结果,我们设计出一种高效的SOC流水总线。通过与支持同样传输协议的总线的性能比较袁明,相对于传统的共享总线,该总线可以节省15%以上的总线时间。该总线已成功地用于一款百万门级32位S(C的设计。

Abstract:

The performance of SoC is based on the efficiency of its bus. We propose a bus performance model which demonstrates the relations between the bus perf ormance and several substantial features of a SoC system. We also present carefully the analysis of the impact which is exerted on the bus performances   by the improvement of the pipeline stages of a bus. We design an efficient pipelined bus from the analysis results, and compare its efficiency with that  of the bus which performs the same transport protocols but do not support the pipeline, and mention one of its implementations on 32-bit SoC with milli  ons of gates.

Key words: (SoC, pipelined busl performance model)
