Design of Computer Composition Principle Experiment BoardBased on CPLD

摘要

In accordance with the problem that the traditional experiment board of computerrncomposition principle can only be used for functional realization and verification, which cannot satisfyrnthe students’ design and innovation, this paper proposes an improved experiment board method ofrncomputer composition principle. This method has used the complex programmable logic device (CPLD)rnchip to replace the original discrete small-scale integration chip; the Quartus II is used to complete therncircuit description by drawing schematic diagram; in the meantime, the control signal board and the datarnpath board are integrated, which form a complete computer system with the microprogrammed board,rnwhich can be used in the experiment teaching. The experimental test results show that the newrnexperiment board based on CPLD has stable and reliable operation, which can realize functionsrnconsistent with the original experiment instrument, and it can be used as the EDA experiment board.
