ABOUT
TiASM (Tiny Assembly) is a tiny assembly like language that I created in order to try and understand how assembly works a little bit better... without writing actual assembly, because as it turns out it's a pain in the ass to do that. This was just a tool to help me out in my Computer Organization and Architecture class in college.
Usage
python tiasm.py <file.s>
System Architecture
- 13 Registers
- r11 contains the output of the CMP/AND/OR/XOR operator
- r12 is the program counter
- 2048 memory locations
- Memory locations 0-1024 are the "Video Memory" or "pixels" on the screen that
- 32x32
- Memory locations 1025-2048 are "RAM" and just for storing information
Instructions
- MOV(eq)(ne) [could be memory address or register]
- CMP [puts result in r11]
- ADD(eq)(ne)
- SUB(eq)(ne)
- MUL(eq)(ne)
- SUB(eq)(ne)
- JMP(eq)(ne)
- AND(eq)(ne)
- OR(eq)(ne)
- XOR(eq)(ne)
Types
i<integer> - Integer
f<decimal> - Decimal
d<register> - Gets the value of the memory address
p<register> - Sets the memory address stored in register to some value
m<memory_address> - Gets the value stored in the memory address
