在最新的PDA、智能手机和手机的高集成应用处理核心中,便携电子的设计创新数量遵从摩尔定律呈指数式增长。从系统设计的角度看,不断增加的功能数量几乎每数年就能翻一倍,与消费者对新功能的无限需求保持同步增长。按照摩尔最初的理论,实现某种系统功能的总成本必须为最小。为了在保持成本的情况下迎接种种设计挑战,采取重新利用现有设计并在其上增加新的功能的做法,这样可以分摊工程设计的费用。今天的系统单芯片(SoC)解决方案承担着满足这些挑战的重任。不断 In the latest highly integrated application processing cores for PDAs, smartphones and cell phones, the number of innovations in portable electronics has grown exponentially with Moore’s Law. From a system design perspective, the ever-increasing number of features can double in almost every few years, keeping pace with the unlimited consumer demand for new features. According to Moore’s original theory, the total cost of implementing a system function must be minimal. In order to meet various design challenges while keeping costs underway, it is possible to share the cost of engineering by reusing existing designs and adding new features to them. Today’s system-on-chip (SoC) solutions take on the challenge of meeting these challenges. Constantly
