现在越来越难以确定16位MCU究竟应包含哪些单元。它是具有16位的数据通路并有通向外界的16位接口的芯片?还是使用16位指令和8位或32位算术逻辑单元(ALU)/数据通路的器件?或是具有8位外部数据通路和16位内部数据通路的电路?抑或是具有16位数据通路且使用可变长度指令的处理器?最新的16位嵌入式控制器向设计师提供了中型处理器的性能,这个性能优于流行的高档8位微控制器(MCU),但其成本没有新的全32位控制器那么高。这些16位控制器现在达到20MIPS的处理速度,为许多系统设计提供了近乎单片逻辑的解决方案,这应归功于更高的集成度和先进的工艺技术:更高的集成度可以把更多的系统功能集成于CPU芯片上,先进的工艺技术使芯片可以使用更高的时钟速度和新的存储器。
It is becoming increasingly difficult to determine exactly which cells 16-bit MCUs should contain. Is it a 16-bit data path with a 16-bit interface to the outside world or a 16-bit instruction with 8-bit or 32-bit arithmetic / logic unit (ALU) / data path devices or with 8-bit external data Path and 16-bit internal data path? Or is a processor with a 16-bit data path and using variable-length instructions? The latest 16-bit embedded controllers provide designers with mid-sized processor performance that outperforms Popular high-end 8-bit microcontrollers (MCUs), but at a fraction of the cost of new full 32-bit controllers. These 16-bit controllers now achieve processing speeds of 20MIPS and offer near monolithic logic solutions for many system designs, thanks to higher integration and advanced process technology: Higher integration can put more The system functions integrated in the CPU chip, advanced technology enables the chip to use a higher clock speed and new memory.
