Using Combinational Circuits for Control Purposes

Maher A. Nabulsi and Mohammed A.F. Al-Husainy


Problem statement: Combinational circuits are used in computers for generating binary control decisions and for providing digital components for data processing. Approach: The use of combinational circuits and logic gates to control other circuits was discussed. Different systems that use logic gates, multiplexers, decoders and encoders to control different circuits were presented. This study presented a design and implementation of some combinational circuits such as a decoder, an encoder, a multiplexer, a bus system and read/write memory operations. Results: When we connected some types of combinational circuits to the inputs/outputs of digital circuit, these combinational circuits can help us to manage and flow a different types of control signals through a large digital circuit. Conclusion: Many combinational circuits had a good function which can be used for controlling different parts of any digital system and they produce a suitable way to transfer a control signals between different digital components of any large digital system.
