音乐播放器，各模块使用VHDL写的，拥有暂停功能。jishu模块根据时钟信号产生八位递增的地址信号，传到music模块。music模块存放音乐的数据，根据得到的地址输出音阶。tonetab接收到音阶信号后会输出当前的音阶是多少，是否为高八度，用于数码管显示，同时将此音阶需要的分频率传给speaker模块。speaker模块根据接受到的分频比对2M的时钟进行分频，然后送给蜂鸣器发出声音。-Music player, each module written in VHDL, with pause function. jishu module generates eight incremented address signal according to the clock signal, transmitted music module. music module storing music data, based on the obtained address output scale. will scale the output signal is received after tonetab current scale is how much is a high octave, for digital display, while the frequency of this scale needs to pass the sub speaker module. speaker module in accordance with the received frequency-dividing the frequency dividing ratio of the clock 2M, and then sent to the buzzer sound.
