[DSP program] low-cost-DSP-realize-MP3-decoding DL : 0: 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.

[DSP program] dsp2812_ad DL : 0: dsp2812 的AD程序含有AD校正，有详细的注释，程序运行正确。2812 内部自带了 12 位，总共 16 路的 AD，这对于需要节省成本的项目来说是一件好事，AD 的价格一般都是比较贵的，2812 的内部 AD 既然能够满足我们的基本需求，也就可以不用另外设计 AD 电路了。但是，由于一些内部的原因，使得 2812 的 AD 精度达不到 12 位的精度，而且误差比较大，为了提高内部 AD 的精度，通常在硬件和软件的角度采用补偿措施对其进行校正，使得其精度能够有所提高，能够满足大多数的应用场合。 -The AD dsp2812 programs contain AD correction, have detailed notes, and the program ran right. 2812 internal take 12, 16 total road, this to the AD for projects that need to save cost is a good thing, AD prices are generally more expensive, 2812 internal AD since can meet the basic needs, we also can need not another AD circuit design. But, since some of the internal reasons, make 2812 AD precision of less than 12 a precision, and the error is bigger, in order to improve the precision of the internal AD, usually in the hardware and the software of the Angle of the compensatory measure calibration, making its accuracy, and can meet to improve most applications.
