History
TIS-100 was released for Windows, OS X and Linux in June 2015 and for iOS 6.0+ in January 2016.
Programming
The TIS-100 has 12 nodes which can be virtual CPUs or stack nodes. The virtual CPU supports 13 instructions, 2 registers, 4 ports and 2 pseudo-ports:
| Instruction | Description |
|---|---|
| NOP | do nothing |
| MOV SRC,DST | copy data from SRC to DST |
| SWP | exchange ACC and BAK |
| SAV | copy ACC to BAK |
| ADD SRC | add SRC to ACC |
| SUB SRC | subtract SRC from ACC |
| NEG | negate ACC (ACC = 0 - ACC) |
| JMP LABEL | transfer execution to LABEL |
| JEZ LABEL | transfer execution to LABEL if ACC = 0 |
| JNZ LABEL | transfer execution to LABEL if ACC ≠ 0 |
| JGZ LABEL | transfer execution to LABEL if ACC > 0 |
| JLZ LABEL | transfer execution to LABEL if ACC < 0 |
| JRO OFFSET | transfer execution to an offset relative to the current instruction |
| HCF | halt and catch file (secret steam achievement command) |
| Name | Description |
|---|---|
| ACC | the accumulator register |
| BAK | temporary storage register |
| NIL | equivalent to 0 |
| UP | communication port to the node above |
| DOWN | communication port to the node below |
| LEFT | communication port to the node on the left |
| RIGHT | communication port to the node on the right |
| ANY | pseudo-port, communicate with the first node which is ready |
| LAST | pseudo-port, communicate with the last node used by ANY |
