【Abstract】 The problem of a traditional experimental instrument for the course of computer principles is that it can only be used for the functions of realization and vertification and cannot meet the requirement for students’ independent design and innovation. A method for improving the experimental board of computer organization is proposed. The method uses a complex programmable logic device(CPLD) chip to replace the traditional discrete small-scale IC chip as the carrier. By using electronic design automation(EDA) tools and very-high-speed integrated circuit hardware description language(VHDL) it can achieve a variety of hardware logic, and connection with the input and output hardware interface circuits. The final composition with a complete computer system can be used for experimental teaching. Experiments show that the new experimental board can achieve the experimental requirements of original experimental instrument, enhance the function of the experimental system, improve flexibility and reduce test costs.更多还原
