多输出组合逻辑电路的简化设计

The Simplified Design of Combinatorial Logical Circuit with Many Output Variables

大多数的组合逻辑电路属于多输出电路 ,在进行多输出电路的设计时 ,由于输出变量增多 ,情况较单输出电路复杂 ,采用一般的设计方法分别对每个输出函数进行设计 ,尽管各个输出电路是最简的 ,但对整个系统来说并不一定最简 ,这时可以从系统整体来考虑 ,采取利用公共项。

The design of combinatorial logical circuit with many output variables is more complex than that with one output variable,because of the more output variables. When the general method of simplified design is adopted,the result is simple for every output variable,but it is also possible for it to be complex for the entire system.In order to obtain simple results,some simplified methods such as using public item, obtaining some output results by other output results and decomposing the system can be adopted.
