### Demonstrate 16 Bit Computer 

### *软件部分：实现了面向对象语言编译器，虚拟机结构，以及如何把面向对象语言编译成虚拟机语言，再把虚拟机语言转换成Hack汇编，最后将Hack汇编转换成二进制的Hack-CPU指令。
### *硬件部分：实现了从AND，OR，NOT等基础逻辑门电路组成ALU，BIT组成PC，RAM等，再一步一步组成HACK-CPU，HACK-Computer。

###   基于FPGA(开源软硬件)实现16位计算机以及其编译工具：

### 硬件：     
   AND OR NOT：基础逻辑门   
   ALU：算术逻辑单元     
   HACK-CPU：中央处理器    
   HACK-COMPUTER: 冯诺依曼架构计算机   

### 软件：  
   Jack Compiler：类JAVA面向对象语言编译器，将Jack语言转成栈虚拟机代码     
   VM Translator：栈虚拟机转换器，将虚拟机码转成HACK-CPU汇编码    
   Hack Assembler：Hack汇编器，将汇编码转成二进制HACK-CPU指令
