本文介紹了一種基于C51 內核的MCU 系統(tǒng)。該系統(tǒng)的設計采用了面向對象的方法。它
包含了一個典型的單片機系統(tǒng)常用的功能模塊：中斷擴展、輸入、輸出控制、數(shù)據(jù)處理、顯示與鍵盤管理等，給用戶提供了一些接口。它具有功能強，效率高的優(yōu)點，并且縮短了單片機系統(tǒng)開發(fā)所需時間。

Abstract：This paper introduces a kind of system of MCU base on C51 core. The design of this system adopts object-oriented technique. It includes some common function modules of a typical system of single-chip microcomputer：interrupt-extension, I/O control, data process, display & keyboard management etc and provides some interfaces for user. It has virtue of strong function , supernal efficiency and shortens development time of single-chip microcomputer system.
