该代码是从外国网上下的，自己懂得的vhdl语言不多，没有亲自去调试设计好像有bug，但毕竟比arm黑盒子强多了！This is very crude variant of ARM core. ARM7TM was used as a prototype for this model. Definitely there are a lot of bugs and holes in it and some features are not implemented for the moment. Features that are not implemented currently:1. Thumb decoder is not implemented (but will be implemented).2. No coprocessor interface.3. Memory interface for the moment indicates non-sequential transactions only.If you find any bug in this core don't hesitate to contact me.Notes:12.02.2003 - The multiplier had been changed but wasn't tested deeply……
