A Combinational Logic Controller Based on Proteus

Da-wei XIAO, Tian-yu HE


Proteus and Keil are used to implement a combinational logic controller. Firstly, the instruction system, instruction flow and control signal of the controller are designed. Secondly, the logical expressions of each control signal are listed and simplified. Then, the circuit schematic diagram of the combinational logic controller is drawn by Proteus software. Finally, using Keil, the program is loaded and run in the controller, which is verified by simulation. This design uses logic devices, improves the execution speed of instructions, and enhances the flexibility of design. In the experiment teaching of Computer Organization course, it can improve students' thinking ability and practical ability well.
