多核处理器S698P-SOC的数据一致性

Data Consistency of S698P-SOC

在多核和多处理器系统中,数据一致性是一个非常重要和关键的问题。影响数据一致性的设计主要包括3个方面:处理器体系结构,Cache算法和软件设计。本文介绍了S698P-SOC多核处理器的体系结构,Cache算法和数据一致性保持机制,讨论了一般情况下的数据一致性问题,介绍了硬件对软件数据一致性设计的支持,并给出了软件设计时的设计要点。相关的技术在工程实践中已经得到验证,获得了良好的效果。

Data consistency is essential in design of multi -cores and multi-processor, the following three aspects influenced the design of data consistency：processor architecture, cache arithmetic and software design. This article mainly introduces the S698P-SOC system structure, cache arithmetic, data consistency, and the hardware holding updata consistency, also provides the key process about design software.
