摘要
本文在调研大量专利文献的基础上,通过跟踪具体专利对微处理器的多核技术进行了深入分析。确定了多核关键技术的发展历程,揭示了不同时期技术要素的特征,以及技术要素的变化,为新产品开发提供线索。特别以多核的两大关键技术(维持Cache一致性和核间通信技术)为例,具体阐述了同一技术的技术演进过程;同时结合中国多核技术的发展现状,预测了多核的发展趋势。
The paper makes a deep analysis on the multi-core technology of micro-processor through tracing some specific patents based on the search of a large number of patents. Then it presents the development of the key multi-core techniques, reveals the characters of the technical elements in different phases, and provides a clue for the exploitation of new products. At last it discusses the development of the same technology specifically on studying the case of two key techniques （ maintaining the coherence of Cache and the inter-core communication ） ; meanwhile it presents the prospect of the multi-core technology regarding the status of the technique in China.
