碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 93 === There are many advantages which allure us to explore contents of asynchronous circuits on asynchronous circuits, such as elimination of clock skew problems, average case performance and lower system power consumption. Furthermore, low power consumption is one of the most important issues for mobile devices. This thesis focus on the implementation of an asynchronous Atmel AVR 8-bit RISC microcontroller. We implement our design with Sutherland’s dual rail DI micropipeline. The whole asynchronous AVR microcontroller was synthesized with current synchronous EDA tools, and realized with FPGA chip. The following instructions were accomplished: arithmetic and logic instructions, such as ADD, SUB, AND, OR; data transfer instructions, such as MOV, LDI; branch instructions, such as JMP. These instructions were used to comprise our asynchronous AVR microcontroller.
