Processor

Processor architecture:

Processor has 8 registers: ax, bx, cx, dx, ex, fx, gx, hx

Processor has acces to RAM: 4k - if you using type int; 8k if you using type double.

The default data type is double. To change type of data in processot you should use defines: #define INT_DATA or #define FLOAT_DATA

Processor instructions:

  • hlt - End of program

  • push - This command have one argument. It push argument value into Stack. push 4 - push constant value into Stack push ax - push register value into Stack push [bx + 5] - push value from address bx + 5 into Stack

  • pop - This command have one or zero argument. It pop value from Stack into argument. pop - pop from Stack pop ax - pop value from Stack into register push [cx] - pop value from Stack into address cx

  • add - adds two last values in Stack (first + second) and push result

  • sub - subtracts two last values in Stack (first - second) and push result

  • mul - multiplies two last values in Stack (first * second) and push result

  • div - divides two last values in Stack (first / second) and push result

  • sqrt - takes square root of value in Stack and push result.

  • out - print last value from Stack

  • in - scan value and push it into Stack

:lable_name - label must start with :

  • jmp lable_name - jumps into the lable

  • ja lable_name - takes two last values from Stack, if first > second jumps into the lable

  • jae lable_name - takes two last values from Stack, if first >= second jumps into the lable

  • jb lable_name - takes two last values from Stack, if first < second jumps into the lable

  • jbe lable_name - takes two last values from Stack, if first <= second jumps into the lable

  • je lable_name - takes two last values from Stack, if first == second jumps into the lable

  • jne lable_name - takes two last values from Stack, if first != second jumps into the lable

:function_name - name of function must start with :

  • call function_name - call function

  • ret - returns from function to the place where it was called

How to use Processor:

Project consists of thre programs: Assembler, Processor and Disassembler.

  • Assembler This programm convert a program in special asm language into binary executable.

Input of Assembler - is a program in special asm language. You should pass a path to asm file in the first argument of programm.

Output of Assembler is a binary executable. You should pass a path to place where you want to see your executable in the second argument of programm.

  • Processor This programm execute a binary executable file received from Assembler.

Input of Processor - is a binary executable. You should pass a path to binary executable file in the first argument of programm.

  • Disassembler This programm convert binary executable file received from Assembler back into asm program.

Input of Disassembler - is a binary executable. You should pass a path to binary executable file in the first argument of programm.

Output of Disassembler is a disassembled file. You should pass a path to place where you want to see your disassembled file in the second argument of programm.
