Automated method of inserting pipeline stages in a data path element to achieve a specified operating frequency

摘要

According to a technique for determining delays through multi- stage datapath elements, estimates of the delays through each stage of the datapath element are computed in accordance with an the equation such as:PPD.sub.s =D.sub.b N.sub.b +CPPwhere D. sub.s is the estimated stage delay, D.sub.b is a delay associated with communication between bits in the stage, N.sub.b is the number of bits in the datapath element, and C is a constant. The estimated stage delays are used to determine positions of pipelining stages in the datapath element.
