| 摘 要： | 目的讨论用中规模器件实现组合逻辑函数时,函数变量数小于数据选择器的地址变量数的情况。方法详细阐述了数据选择器的原理及应用,从逻辑函数表达式、真值表和卡诺图3方面进行分析。结果得出用MSI数据选择器设计组合逻辑函数能够实现任意组合逻辑函数,并通过实例验证了其有效性。结论用MSI数据选择器可实现任意组合逻辑函数。

| Abstract: | Aim When using moderate dimension of apparatus to realize combined logic function,the instance which function variable numbers is less than the address of data selector is discussed.Methods The principle and application of data selector is analyzed from logic function expression true value list and karnarph mapping.Results A conclusion can be drawn that using MSI data selector to design combined logic function can implement any combined logic functions.Some practical examples are validated to its validity.Conclusion Using MSI data selector can implement any combined logic functions. |
