In this paper, we present how to optimize our ARM7TDMI instruction set compatible microprocessor. The ARM7TDMI is a 32-bit microprocessor developed by ARM Ldt. It used in embedded application such as mobile phones, pager and PDAs. The ARM7 family owes its success to the combination of low power, low cost and high performance. However, as applications become more complex and integrate more and more functionality, the processor is required to provide more and more performance. We tune the hardware simply, no use complex hardware, to complete performance optimization. We use synthesis tool to synthesize our RTL design and analyze timing to fund the critical path of our microprocessor. We will describe how to optimize the critical path to increase performance.

In this paper, we will explore architecture variations of ARM7 microprocessors. The ARM7TDMI is a 32-bit microprocessor developed by ARM Ltd. It used in embedded application such as mobile phones, pager and PDAs. However, as portable products grow in complexity more processing power is required. This paper focuses on the implementation of the architecture variations of ARM7 microprocessors. The evolutions from our RTL design to architecture variations are described and the trade offs between high performance and low gate count discussed.

The work deals with the 32-bit microcontroller with AT91SAM7X256 ARM7 core. The overall purpose of the thesis is to use the microcontroller as a data logger in Orpheus robotic system. The main part of the work focuses on detailed description of the designed board, software and development environment. A comparison of different varieties of the microcontroller with this core is included.
