Abstract: The fixed-length number is one of the important theories in generation and development of the computer. In this paper, it is given the definitions of the symmetric digital and the base complement. It shows the principle of the addition or subtraction with the fixed-length number’s addition within a certain range of values. It gives the methods of the design of arbitrary binary calculator for addition or subtraction and the expansion of the value's scope. It is simple and easy to use the fixed-length number to design computer.
Key words: computer system architecture; fixed-length number; base complement; symmetric digital; arithmetic device; computer design
