Design of Time-Triggered Embedded System based on ATmega128 / 医疗卫生装备

ABSTRACT

Objective To develop an embedded system by using time-triggered system and ATmega128.Methods Making use of the minimum system structure of ATmega128,a multitask system,which could be implanted into AVR CPU,was designed based on the singlechip with 8 bits and 51series.Results Time-Triggered Embedded System kept the controlling precision on ms degree and ensured a sensitive and rapid response to keyboard input.Conclusion Software designed by Time-Triggered Embedded System has advantage in real time,so it is applicable to minitype real time control system.
