Especially the monolithic integrated circuit technologys application product already entered everyone, if the electronic ten thousand calendars appearances have brought conveniently many for peoples life. This article described the system hardware principle of work, and attaches by the system structure diagram explained that introduced emphatically this system applies various hardware and connection technology and various hardware module function and work process; Next, elaborated in detail procedure each module and realizes the process. This design take the digital integrated circuit technology as the foundation, the monolithic integrated circuit technology is a core. The compilation guiding ideology software and hardware unifies, take the hardware as the foundation, carries on various functional module the compilation. This system for ease of the expansion and the change, softwares design uses the modular structure, causes the programming the logical relation even more simple and brief. System throug
