用verilog编写的ARM7内核代码，通过modelsim仿真-With verilog code written in ARM7 core, through the modelsim simulation

基于arm-v4架构，兼容ARM7指令集。附录有说明文档，希望对大家有用。可以在windows上使用Debussy+modelsim的组合开发，是Verilog写的-Based on arm-v4 architecture, compatible with ARM7 instruction set. Appendix have documentation, we hope to be useful

FPGA作为从机与STM32的全双工通信，FPGA将接收到STM32的数据返回到STM32，Modelsim仿真和板子仿真都通过(Use FPGA as slave,realize the communication between FPGA and STM32. The function has been tested is no problem.)
