微控制器针对每个应用程序的性能路线图

　　微控制器针对每个应用程序的性能路线图

　　对性能的需求是直观的，特别是在开发嵌入式应用程序时。大多数设计团队面临的挑战是知道有多少性能是足够的，本质上依赖于两件事情：所需的功能，以及如何实现。虽然实现主要是在软件中，微控制器的价值的一部分是外围设备做了大量的重载方面的接口。然而，操纵这些接口提供的信息正给核心本身增加压力和压力。

　　更大的性能是以成本为代价的，但由于微控制器往往是建立在行之有效的工艺节点，成本往往是衡量系统级的权力，而不是组件级美元和美分。

　　选择最佳的微控制器为一个给定的应用程序可以说是变得更加困难的广度和深度的功能继续扩大，符合最终用户的需求。

　　The evolution of MCU applications

　　Leading semiconductor vendors have faced a period of adoption over the last decade or so， towards offering a comprehensive portfolio of MCUs based on 32-bit processing cores. Although ARM®’s Cortex™-M family is endemic in this space， it is not the only option and several proprietary architectures still exist. Perhaps one of the most prominent is theSuperH family from Renesas. It is interesting to note that while Renesas and other companies have also adopted the ARM architecture to produce complementary 32-bit families， they still offer 8- and 16-bit MCUs， for which demand is anticipated to continue for several more years.
