【摘要】 在FPGA开发平台上,根据需求分析来配置MicroBlaze微处理器,并对微处理器与外围电路的接口进行了研究。使用C语言模拟串行总线I2C,来完成FPGA与加速度之间的数据传输和控制;同时模拟串行总线SPI,来完成FPGA与语音模块之间的数据通信;并通过点阵图形液晶显示模块实现人机交互。最后经过实验测试证明三轴加速度数据的实时采集和处理效果良好。更多还原

【Abstract】 The MicroBlaze microprocessor was configured according to the requirement analysis.The interface was studied between microprocessor and peripheral circuits in the platform of FPGA(Field Programmable Gate Array).The data between FPGA and the module of acceleration acquisition was transmitted and controlled by the serial bus of I2C which was simulated by the language of C.At the same time,the data between FPGA and the module of audio acquisition was transmitted by the serial bus of SPI.And the interaction of human-computer was implemented by the module of LCD.At last,the data of the three-axis acceleration was acquisited in real time,and the result did correspond with our preliminary design.更多还原
