在嵌入系统的世界里,微处理器与微控制器之间的界限已经变得模糊了,这是因为处理器核是作为系统的一部分与其它部分设计在同一块芯片上的,且各部分间有着自由的联系。带有内部知识产权的大公司能够经常使用新的处理器核来重新利用其(产品的)外围部分。这样一来。几乎所有的产品都是一个微控制器,它们在芯片上都带有各自的外围部分。 通过规范专有的片上总线以便于重 In the world of embedded systems, the boundaries between microprocessors and microcontrollers have become obscured because the processor cores are designed on the same chip as the rest of the system as part of the system, and the parts Have a free connection. Large companies with internal intellectual property can often use the new processor core to reuse their (product’s) peripheral parts. Thus. Almost all products are a microcontroller, they have their own chip on the periphery. By regulating the proprietary on-chip bus to facilitate heavy
