ASSEMBIY VARIABIES REGISTERS Unlike HlL like C or java, assembly cannot use variables Why not? Keep hardware simple Assembly operands are registers Limited number of special locations built directly into the hardware Operations can only be performed on these registers. Benefit: Since registers are directly in hardware, they are very fast (faster than I ns-light travels 30cm in l ns!!!)▪ Unlike HLL like C or Java, assembly cannot use variables ▪ Why not?
