One Prediction-implementation , Generalization , and Application

  title={One Prediction-implementation , Generalization , and Application},
  author={Nhon T. Quach and Michael J. Flynn},
This paper presents the concept of leading-one prediction (LOP) used in most high-speed floating-point adders in greater detail and describes two existing implementations. The first one is similar to that used in the TBM RS /GO00 processor. The second is a distributed version of the first, consuming less hardware when multiple patterns need to be detected. We show how to modify these circuits for sign-magnitude numbers as dictated by the IEEE standard. We then point out that (1) LOP and carry… CONTINUE READING
