Mega16是一款采用先進RISC精簡指令，內置A/D的8位單片機，可支持低電壓聯機 Flash和EEPROM 寫入功能；同時還支持 Basic和C 等高級語言編程。用它設計電子時鐘不僅成本低，硬件簡單，而且很容易實現系統移植。介紹了如何利用AVR系列單片機Mega16及1602字符液晶來設計電子時鐘的方法，同時給出了相應的電路原理及部分語言程序。
Abstract:
?Mega16 is a high-performance, low power consumption, the use of advanced RISC concise instructions, built-in A/D 8-bit microcontrollers, the on-line support for low-voltage Flash, EEPROM write function. Except Mega16 also support the Basic, C, and other high-level language programming.The electronic clock which is deisgned by Mega16 is not only low-cost, simple hardware, but easy to achieve system migration.The design method of electrioic clock based on the AVR Mega16 and character LCD1602 is introduced in this paper,and the corresponding circuit electrionic and some language program are given.
設計了一款基于Avalon總線的8051MCU IP核。它支持MCS-51指令集，優化內部的結構，通過采用流水線技術、指令映射技術、指令預取技術、微代碼技術等極大的提高了IP核的工作速度，使IP核在100MHz時鐘下，能夠單周期執行一條指令。本設計使用Modelsim軟件完成了功能仿真和時序仿真，并在以Altera 公司的Cyclone II FPGA芯片為核心的DE2開發板上完成了硬件驗證。
