ASIA

ASIA, short for ArchEvo Standard Instruction set Architecture, is an ISA in ArchEvo. It was the original ISA that was created for ArchEvo. It was the only ISA supported in ArchEvo Classic, and is currently the only available ISA in ArchEvo Pangea, although research is being done on it's successor.

Instructions

ASIA instructions are eleven bits long.

OOO22221111
O - Opcode
1 - Register 1
2 - Register 2

Operations

ASIA uses the Ghost Bit system, so while there are only three bits of opcode, there are 16 possible instructions.

GB	Opcode	Command	Description	Action Type
0	000	INC <reg1>	Increments reg1	RegisterUpdate
0	001	DEC <reg1>	Decrements reg1	RegisterUpdate
0	010	SLL <reg1>	Shifts reg1 left	RegisterUpdate
0	011	SRL <reg1>	Shifts reg1 right	RegisterUpdate
0	100	MOV <reg1> <reg2>	Move value of reg2 to reg1	RegisterUpdate
0	101	SLT <reg1> <reg2>	Set reg1 to 0xFF if reg1 < reg2 else 0x00	RegisterUpdate
0	110	SGT <reg1> <reg2>	Set reg1 to 0xFF if reg1 > reg2 else 0x00	RegisterUpdate
0	111	SET <reg1> <reg2>	Set reg1 to 0xFF if reg1 = reg2 else 0x00	RegisterUpdate
1	000	REP	Reproduce at IPLOC	Reproduce
1	001	JMP	Jump	MoveInstructionPointer
1	010	JMC <reg2>	Jump if reg2 = 0xFF	MoveInstructionPointer
1	011	MOV	Move cell in direction of IPLOC	Move
1	100	NON	UNASSIGNED	DoNothing
1	101	NPA	NOP A, part of jump templating	DoNothing
1	110	NPB	NOP B, part of jump templating	DoNothing
1	111	ATK	Attack cell at IPLOC	Attack
