山东省威海市戚正义问:80C51系列单片机在片内集成了那些主要逻辑功能部件?各个逻辑部件的主要功能是什么? 答:80C51系列单片机在片内集成了以下主要逻辑功能部件及相应的逻辑部件的主要功能: (1)CPU(中央处理器):8位中央处理器由中央控制器与运算器一起构成。中央控制器是识别指令,并根据指令性质控制计算机各组成部件进行工作的部件。 (2) 片内RAM: 128 B 在单片机中,用随机存取存储器(RAM)来存储程序在运行期间的工作变量和数据,所以称为数据存
Qi Zhengyi, Weihai City, Shandong Province Q: 80C51 series microcontrollers integrated in the chip those main logic features? What is the main function of the various logic components? A: 80C51 series microcontroller integrated in the chip the following main logic features and the corresponding logic Parts of the main functions: (1) CPU (CPU): 8-bit central processor with the central controller and the operator together. The central controller is a unit that recognizes instructions and controls the operation of the computer’s components based on the nature of the instruction. (2) on-chip RAM: 128 B in the microcontroller, with random access memory (RAM) to store the program during the operation of the working variables and data, so called data storage
