this ALU has 3 operation wich are 'or' and 'and' and 'add' and 'subtract'

Logic diagrams for nand2tetris part 1 (projects 1 to 6).

This is part of a project to construct a 4 BIT CPU from scratch. I will be starting with a simple NOR gate and building it up to a working model with ALU registers, RAM and ROM. I will be designing an op code and assembler to go with it. Progress and detail can be found on my blog here

This file contains the ALU

This is a CPU witch is capable of executing a lot of stuff in one clock cycle, and this CPU can shift left up to 7 times and shift right up to 7 times witch means that it is possible to  multiply and divide in one clock cycle if you program a table in the program memory. it has a 32 bit instruction width and a 8 bit address. it also has 

The ALU has the following operations:

• ADD
• SUBTRACT
• SHIFT_LEFT (up to 7 times per cycle 3 bit)
  
• SHIFT_RIGHT (up to 7 times per cycle 3 bit)
  
• XOR
• OR
• NOT
