ABSTRACT:
The present invention provides a method and an apparatus for performing multiply operation of floating point data in 2-cycle pipeline scheme, which can be applied to pipelined data path so that it is always capable of processing floating point data as long as the data is not contiguous, for reducing the area of the multiplier by reducing the number of basic cells used to 1/3 of that of basic cells used in conventional techniques. The present invention for multiplying floating point data includes the steps of: (a) receiving multiplier data and multiplicand data from pipelined input in the first cycle of multiply operation; (b) generating a partial product by means of the multiplier data and multiplicand data, and generating a first sum and a first carry by adding the partial product through an adding tree circuit; and (c) generating an output of the multiply operation by adding a second sum and a second carry to the first sum and the first carry, wherein the second sum and the second carry are generated by feedbacking the first sum and the first carry in the second cycle of the multiply operation which succeeds the first cycle.
