半導體行業已經大致按照摩爾定律發展了半個多世紀，對二十世紀後半葉的世界經濟增長做出了許多的貢獻，驅動了一系列的新科技、生產效率的提高和經濟成長。個人電腦、網際網路、智慧型手機的改善與創新都離不開半導體產業的進步。 電腦、手機和家電的CPU、GPU等許多零件，都是以電晶體為基本元件所構成的邏輯電路，因此有關邏輯電路的基本知識就變得十分重要，在邏輯電路中，組合邏輯電路和序向邏輯電路，兩者最大的差別在於記憶元件的有無，所以在組合邏輯電路中輸出只和當前輸入有關，而序向邏輯電路的輸出不僅與當前輸入有關還與前一時刻輸入有關。在現代的電子產品中大多由序向邏輯電所控制，原因就是記憶元件。而組合邏輯電路主要作邏輯代數運算之用。但在部份的序向邏輯電路問題中，是否存在組合邏輯的解呢?論文中將會簡單介紹組合邏輯電路和序向邏輯電路，並在部份的序向邏輯電路中找出組合邏輯解。 ;The semiconductor industry has been developing roughly in accordance with Moore′s Law for more than half a century, contributing to world economic growth in the second half of the twentieth century. Drive a range of new technologies, productivity gains and economic growth. The improvement and innovation of personal computers, the Internet and smartphones are all dependent on the progress of the semiconductor industry. Many parts, such as CPUs and GPUs for computers, mobile phones and home appliances, are logical circuits consisting of crystal bodies as basic components, so the basic knowledge of logic circuits becomes very important. In logic circuits, the biggest difference between the combinational logic circuit and the sequential logic circuit is whether there is a memory element, so the output in the combinational logic circuit is only related to the current input, and the output of the sequential logic circuit is not only related to the current input but also related to the previous moment input. Most of modern electronic products are controlled by sequential logic, because of memory elements. The combinational logic circuit is mainly used for logic algebra operation. But in some of the sequential logic circuit problems, is there a solution to the combinational logic? The paper will briefly introduce the combined logic circuit and the sequential logic circuit, and find the combinational logic solution in the partial sequence logic circuit.
