采用符号替换的先行进位光学并行全加器的研究

Parallel Full-Adder with Optical Sysmbolic Substitution

提出了新的符号替换逻辑操作方法,实现与门、或门、异或门等基本逻辑操作。将这些符号替换逻辑操作应用于先行进位光学并行全加器中,实现了多位二进制数的光学并行全加器,显示了符号替换操作在并行处理方面的优势。

The new method of logic operations based on the symbolic substitution isproposed.The basic logic operations,such as the AND gate,OR gate and XOR gate,have beencompleted.The full-adder for multi-bit binary numbers can be realized by applying the logicoperations with symbolic substitution to the carry-look-ahead optical parallel processing.Thesuperiority of the symbolic substitution in parallel processing is shown.
