illustrate the effectiveness of pipelining without having to deal with some of the complex issues involved in instruction pipeline design These complex issues will be addressed in subsequent sections of this chapter 2121 FloatingPoint Multiplication The design of a pipelined floatingpoint multiplier is used as the example This "vintage" boardlevel design is taken from a classic text by Shlomo Waser and Mike Flynn [Waser and Flynn, 1982] (Even though this design assumes 1980 technology, nonetheless it still serves as an effective vehicle to illustrate arithmetic pipelining) This design assumes a 64bit floatingpoint format that uses the excess128 notation for the exponent e (8 bits) and the signmagnitude fraction notation with the hidden bit for the mantissa m (57 bits, including the hidden bit) The floatingpoint multiplication algorithm implemented in this design is as follows 20 30 Pipeline depth k
