Description: SD卡和AIC23数字音频输出实验, FreeDev Audio Dsp Board采用了TI公司的TVL320AIC23
1、控制接口使用I2C，Quartus中将CS置低（器件地址0011010）。 2、数字音频接口使用了组件FreeDev_aic23,有三种测试和应用
模式，中断结合DMA方式能在NIOS II中采集和发送数据。中断信号 产生于模块中FIFO缓冲区的半满信号，读取数据端口自动清除中断
请求信号。 3、I2C IP 和FreeDev_aic23 IP分别在Quartus 工程目录中 4、SD卡读写通过SD_DAT0、SD_CLK、SD_CMD三个PIO信号线用软件 控制时序。 5、该范例读SD卡数据，通过DMA将Buffer数据送到FreeDev_aic23的
FIFO中实现数据播放。 6、SD卡中的数据必须是以48K*16bit保存的采样数据。数据可以通过SD读卡器写入。

Description:
With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

Description: DSB-SC信号的生成与解调
1) 用离散（DSP）的方法生成DSB信号
2) 载波频率为150KHz，音频为500Hz和2000Hz的混合音。
3) 加入高斯白噪声
（4） 语音信号
的传输。
改变抽样频率和量化台阶大小，观察重建信号以及量化噪声信号的波形；对于语音信号主观评价声音质量的变化。
-DSB-SC signal generation and demodulation 1) Discrete (DSP) methods to generate DSB signal 2) the carrier frequency to 150KHz, audio 500Hz and 2000Hz for the mixed tone. 3) by adding white Gaussian noise (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.

Description: 首先介绍了MPEG－2音频layer Ⅲ（MP3）的解码算法，详细地叙述进行定点C语言仿真的技巧。基于TI公司的’C549 DSP芯片进行汇编工作，在TMS320C549 EVM板上实现了网上MP3文件的连续播放，效果满意。经过对算法和程序的优化使所需的运算量和存储空间都很低，使能在TI公司的低价型’C5402 DSP上实现。-First introduced the MPEG-2 audio layer Ⅲ (MP3) decoding algorithm, a detailed account of the fixed-point C-simulation techniques. Based on TI' s' C549 DSP chip assembly work in TMS320C549 EVM board to achieve an online MP3 file of continuous playback, the effect is satisfactory. After the optimization of algorithms and procedures to make the necessary computation and storage space are very low, so low in TI' s type ' C5402 DSP to achieve.
