Introduction

In this repo are projects from the book ARM9-compatible CPU soft core design based on FPGA (《兼容ARM9的软核处理器设计：基于FPGA》https://baike.baidu.com/item/兼容ARM9的软核处理器设计%EF%BC%9A基于FPGA/1686845?fr=aladdin).

Contents

Up to now I have successfully replicated all the experiments in this book:

Chapter 2 Verilog RTL programming

• Section 2.5 UART serial communication (in folder "UART_serial_communication")

Chapter 7 Run "Hello World" on ARM9 compatible CPU core

• Section 7.2 Compile "Hello World" program with RealView MDK-ARM ("LPC2101_Hello")
• Section 7.3 Output "Hello World" in simulation ("ARM9_HelloWorld")
• Section 7.4 "Hello World" project for FPGA ("ARM9_HelloWorld")

Chapter 8 Dhrystone Benchmark on ARM9 compatible CPU core

• Section 8.2 Porting Dhrystone 2.1 to FPGA ("LPC2104_DHRY")
• Section 8.3 Dhrystone Benchmark in RTL simulation ("ARM9_Dhrystone")
• Section 8.5 Dhrystone Benchmark on FPGA board ("ARM9_Dhrystone")

Chapter 9 uClinux simulation - booting non-MMU OS in reference to SkyEye

• Section 9.4 SkyEye hardware simulation platform ("skyeye-testsuite-1.2.5")
• Section 9.5 Boot uClinux in RTL simulation ("ARM9_uClinux_simulation")

Chapter 10 Linux simulation - booting OS with MMU in reference to FriendlyARM Mini2440 board

• Section 10.6 Boot Linux in simulation ("ARM9_mini2440_Linux_simulation")

... and is currently working on Chapter 6 Verilog RTL design of ARM9 compatible CPU core.

My report report.pdf consists of two parts: summary of book content; my experimental results.

Note

• xpr projects are to open with Vivado 2015.4 and its simulator, except that "ARM9_mini2440_Linux_simulation" requires Modelsim 10.6 (it fails on Vivado 2015 simulator); uvproj projects are to open with μVision>=4, and the "skyeye" stuff is to run in SkyEye under Ubuntu. My operating system is Windows 10, and my FPGA board is Digilent Nexys4 DDR.
• The majority of code are downloaded from https://code.google.com/archive/p/risclite/ and https://code.google.com/archive/p/arm-cpu-core/, which are provided by book author; however, those projects are based on obsolete platforms such as Xilinx ISE, and I spent effort to make them runnable on Vivado on Windows 10.
• This repo requires Git LFS (large file support)
