便于优化设计的有权码和编码方式

Weighted Code and Coding Mode for Optimal Design

本文探讨了编码中的各种有权码,以及在权相同的情况下表示十进制数的各种不同编码方式,从而求出不同编码方式数的公式。知道了各种编码方式后,就可以从中选用器件少、易于实现而又满足要求的编码方式,进而优化设计。

In this paper, a variety of weighted code and the different coding mode representing a decimal number with the same weight are investigated first. Then the formulas, with which every possible number of coding mode can be calculated,are derived. Finally, having known the different coding mode,we can choose the best one in the sense of using less devices and easy being implemented to meet the specifications desired, and therefore to optimize the design.
