摘要：The present invention provides a method and an apparatus for performingmultiply operation of floating point data in 2-cycle pipeline scheme, which can be appliedto pipelined data path so that it is always capable of processing floating point data aslong as the data is not contiguous, for reducing the area of the multiplier by reducing thenumber 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 ofmultiply operation; (b) generating a partial product by means of the multiplier data andmultiplicand data, and generating a first sum and a first carry by adding the partialproduct through an adding tree circuit; and (c) generating an output of the multiplyoperation 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 firstsum and the first carry in the second cycle of the multiply operation which succeeds thefirst cycle.
