ABSTRACT:
An instruction encoding method is provided for communication between devices. Before transmission, each opcode is multiplied by two. Each operand is multiplied by two and incremented by one. Encoded opcodes and operands are sent as rising edges (i.e., voltage transitions) on a single wire connecting transmitting and receiving devices. The receiving device counts the rising edges to form a total. Even totals correspond to opcodes, odd totals correspond to operands.
