自 动 控 制 专 业 英 语 论文 论文题目:Working Process Of The 51 Microcontroller 系 、 部： 电气与信息工程系 学生姓名： 唐正 指导教师： 李欣 专 业： 电气自动化 班 级： 电气0902班 学 号： 09400130212 完成时间： 2011年5月19日 Abstract SCM is an integrated circuit chip, ultra-large scale integrated circuit technology is used with data processing capabilities to the central processing unit CPU random access memory RAM, read-only memory ROM, a variety of I / O port and interrupt system, timers / timer Other functions (and possibly the display driver circuit, pulse width modulation circuit, analog multiplexers, A / D converter circuit) into a single silicon wafer consisting of a small but complete computer system.（附图）如下： Working Process Of The 51 Microcontroller  SCM automate the process of the task entrusted to it, that is, the process of SCM implementation procedures, that a section of the process of implementation of the directive, the so-called requirements of MCU instruction is to perform various operations in the form of the command used to write down, which is in the design instruction given to it by persons determined, a command corresponding to a basic operation; single chip can perform all the commands that the microcontrollers instruction set, different types of microcontrollers, the command system is also different. To enable a microcontroller to automate specific tasks, to solve the problem must be compiled set of instructions (these instructions must be able to identify and execute the selected MCU instructions), this series has become the program set of instructions, procedures need to pre- stored in a storage components - memory. Memory by a number of storage units (the smallest unit of storage), with just as big as the building composed of many rooms, the instruction is placed in these units, the units in the instruction and perform like big buildings out of each room is assigned
