Simple processor realisation with assembler and disassembler. Under construction
On linux, you can build using CMake
cmake -S ./ -B out && cmake --build out
Run CPU, filename is path to code in pseudo-asm
out/cpu <filename>
or
out/executable e <filename>
Run assembler, input is path to file with code in pseudo-asm, output - path to file where bytecodes will be written
out/asm <input> <output>
or
out/executable a <input> <output>
Run disassembler, input is path to file with bytecode, output - path to file where code in pseudo-asm will be written
out/disasm <input> <output>
or
out/executable d <input> <output>
There are example files in assets folder

| in | 05 | Reads double value from console and pushes to stack |
| out | 06 | Pops last value from stack and writes to console |
| pop | 07 | Pops last value from stack |
| push | 08 | Pushes double value to stack |
| pop | 09 | Pops last value from stack and writes to given register (ax, bx, cx or dx) |
| push | 0a | Pushes value of given register (ax, bx, cx or dx) to stack |
| jmp | 0b | Unconditionally jumps to the label |
| ifl | 0c | Pops two last values from stack and jumps to given label if second popped value is less then the first one |
| ifle | 0d | Pops two last values from stack and jumps to given label if second popped value is less then or equal to the first one |
| ifg | 0e | Pops two last values from stack and jumps to given label if second popped value is greater then the first one |
| ifge | 0f | Pops two last values from stack and jumps to given label if second popped value is greater then or equal to the first one |
| ife | 10 | Pops two last values from stack and jumps to given label if second popped value is equal to the first one |
| ifne | 11 | Pops two last values from stack and jumps to given label if second popped value is not equal to the first one |
| call | 12 | Saves current position in call stack and jumps to given label |
| ret | 13 | Returns to the last saved position in call stack, just after the last executed call command |
| hlt | 14 | Stops the execution |
