ASIA-16

ASIA-16 is an ISA, and a successor to ASIA. Each instruction has 16 bits, while ASIA only has 11. Of the five extra bits, four are a new register reference and one is an extra bit of opcode. As there are now three registers, each register reference is four bits and each register holds eight bits, two registers can be put together into a constant, and also have room for a register.
