随着知识经济的蓬勃发展,知识产权(IP)这个名词已经为人们越来越熟悉,而知识产权的授权使用则一方面成为知识形态的产品进入商品交易的主要形式,同时也成为知识产权保护的主要手段;另一方面,它也成为知识产权(IP)供应商构筑技术壁垒,实现技术垄断乃至市场垄断谋取高额利润的必要手段,本文以作者在知识产权(IP)起关键作用的集成电路设计行业的亲身实践经验,通过对国际IP巨头的业务运作模式的分析,探讨我国正在迅速发展的集成电路设计业如何应对国外(IP)供应商构筑的技术壁垒,争取以合理的成本合法地获取国外知识产权(IP)从而实现跨越式发展,以及建立我国自身的IP产业的必要性及其面临的挑战和机遇,而在其过程中,对于急需获得IP授权完成芯片设计的Fabless设计公司而言,相信本文披露的一些IP厂商经营之道一定能帮助您把握市场先机,获得在IP授权交易中的主动权.…… 相似文献

Distributed Coordination Function (DCF) is the basis of IEEE 802.11 MAC sublayer. To improve energy efficiency, IEEE 802.11 has specified power saving mechanism (PSM) for DCF. However, the performance of PSM degrades seriously when load is heavy. In this paper we first analyze the reason of performance degradation, and then propose two adaptive mechanisms: PSM+ and fairPSM+. Numerous simulation results have shown that these two mechanisms can achieve high performance with heavy load and still get the same performance as PSM when load is light.Shihong Zou was born in 1978.

《Spectrum, IEEE》1990,27(10):34-39
The ways in which the various components of corporate R&D have changed in response to escalating worldwide competitiveness, (with basic research remaining more or less untouched) are examined. Some lessons learned by R&D executives about how to be first with the best are noted, and various attempts to streamline corporate R&D are described. These include giving business divisions a greater role in selecting R&D projects, decentralizing R&D efforts, having research teams and development teams work jointly on common goals, joint ventures, and working with universities. Measuring the R&D payoff is discussed, and some shortcomings of R&D in various countries as perceived by corporate executives are indicated 相似文献
