4、n the early 1990s, it changed the dynamics of the semiconductor industry forever. By licensing, rather than manufacturing and selling its chip technology, the Company established a new business model that has redefined the way microprocessors are designed, produced and sold 2.,5,2.通过许可，而不是制造和出售它的芯片技
5、术，公司重新定义了微处理器设计、生产与销售的方式，从而建立了一种新的商业模型。 By licensing, rather than manufacturing and selling its chip technology是状语，可译为“通过许可，而不是制造和出售它的芯片技术”。 More importantly, ARM has shaped a new era of next-generation electronics: ARM Powered microprocessors are pervasive in the electronic products we use,6,drivin
6、g key functions in a variety of applications in diverse markets, including automotive, consumer entertainment, imaging, industrial control, networking, storage, security and wireless. ARM licenses its IP to a network of Partners, which includes some of the worlds leading semiconductor and system com
7、panies, including nineteen out of the top-twenty semiconductor vendors worldwide.,7,These Partners utilize ARMs low-cost, power-efficient core designs to create and manufacture microprocessors, peripherals and SoC solutions. As the foundation of the companys global technology network, these Partners
8、 have played a pivotal role in the widespread adoption of the ARM architecture and to date; ARM Partners have shipped more than one billion ARM microprocessor cores.,8,To support and complement the companys RISC microprocessor cores and SoC IP, ARM has developed a strong software capability. Partner
9、s have access to an unrivaled range of software-based IP, operating systems (OS) ports and software design services. In this way, ARM provides Partners with a full portfolio of offerings that deliver significant risk reduction and faster time-to-market benefits 3.,9,3.通过这种方式，ARM提供给合作伙伴一整套旨在降低风险并能快速获
10、取市场利益的投资物。 that deliver significant risk reduction and faster time-to-market benefits是定语，修饰a full portfolio of offerings。 In order to support this global technology network, ARM has recently introduced two significant technology advancements that are already in use by key semiconductor companies.,10
