文章给出了矩形乘法器的另一个结构设计，该设计在计算速度上优于文献[1]的方案而劣于文献[2]的方案，在流水线分级方面则比文献[2]的方案有灵活性。这一实现把大整数乘的数据相关之时间代价降为1个二选一选通器加上3位加法器所需的时间，即把乘法器流水线的节拍时间值降到了该值，从而大大提高了用流水线实现大整数乘的效率。在某些应用中，用矩形乘法器来实现平行四边形乘法器的功能，则可大大降低规模。
The article presents another structural design of the rectangular multiplier, which is superior to the scheme of [1] in terms of computational speed and inferior to the scheme of [2] in terms of computational speed, and has more advantages in terms of pipeline classification than the scheme of [2] flexibility. This implementation reduces the time-related cost of large integer multiplication data to the time required for a two-to-one selector and a three-bit adder to drop the beat time of the multiplier pipeline to a significant value Improve the efficiency of using pipelining to achieve large integer multiplication. In some applications, rectangular multipliers to achieve the function of parallelogram multipliers, you can greatly reduce the size.
