基于VLSI平台的AVR处理器仿真与设计
Simulation and design of AVR processor based on VLSI platform
摘要
Abstract
Internal limited logic resources and external fixed⁃pin package of traditional microprocessors greatly limit their application range. The internal structure,memory management structure and instruction set architecture of micro control unit (MCU)are described. The abundant logic resources of field programmable gate array(FPGA)are used to virtualize the proces⁃sor core of traditional MCU. Wishbone bus is added to connect processor core with common peripherals to form a virtual MCU platform. Moreover,the bottom⁃up design of AVR core is performed with hardware description languages such as Verilog and VHDL,which is connected with common peripherals to build a system. Board level validation was carried out with XILINX Vir⁃tex⁃II Pro chip. The result shows that the set objective is achieved and the system which runs stable is compatible with standard MCU. This method continues the vitality of traditional MCU,and makes it further progressed.关键词
