— The load upper immediate instruction lui loads the highest 16 bits of a register with a constant, and clears the lowest 16 bits to 0s. This illustrates the principle of making the common case fast. — Most of the time, 16-bit constants are enough.
The example project has instances of the four logic operations directly supported by the instruction set: and, or , nor, and xor. There is also an instance of the not pseudo-instruction.
Move operation
The move operation (simple register transfer) is a pseudo-instruction, shown in the instance below taken from the example project:
