WebThe addu instruction mechanically grinds through the Binary Addition Algorithm, producing a 32-bit result from two 32-bit operands. Overflow is ignored (that is what the "u" at then end of the mnemonic means). There is another instruction, add, which causes a trap when two's complement overflow is detected. Other than that, it is the same as addu . Webinstruction name, or mnemonic, for the instruction, instead of the binary value for the instruction. Our binary instructions are called machine instructions. The corresponding mnemonic instructions are what we refer to as assembly language instructions. There is a one-to-one correspondence between assembly language and machine instructions.
