基于SoPC的嵌入式二维条码识读系统使用集成在QuartusII中的SoPC Builder开发组件配置生成片上系统,结合降噪处理、背景分离 图像校正、图像二值化、码字识别、信号纠错等技术，处理由OmniVision OV7649 CCD产生的条码图像。-SoPC based embedded system uses two-dimensional bar code reader integrated in QuartusII development of SoPC Builder component configured to generate system-on-chip, combined with noise reduction treatment, the background separation image correction, image binarization, character identification code, the signal error correction technologies such as treatment by the OmniVision OV7649 CCD barcode images generated.

1. 完成时／分／秒的依次显示并正确计数，利用六位数码管显示； 2. 时／分／秒各段个位满10正确进位，秒／分能做到满60向前进位，有系统时间清零功能； 3. 定时器：实现整点报时，通过扬声器发出高低报时声音； 4. 时间设置，也就是手动调时功能：当认为时钟不准确时，可以分别对分／时钟进行调整； 5. 闹钟：实现分/时闹钟设置，在时钟到达设定时间时通过扬声器响铃。有静音模式。 -1. Completed/min/sec display and correctly followed by counting, using six digital tube display 2. When/min/sec in the paragraphs of the correct 10-bit binary full, s/sub can do to advance the age of 60-bit, systematic function of the time cleared 3. timers: realize the whole point of time, by the time the level of sound from loudspeakers 4. time settings, which is manually adjusted when the function: When the clock does not consider accurate, they can respectively sub/clock adjustments 5. alarm clock: the realization of sub-/ when the alarm clock settings, settings in the clock arrival time ringing through the loudspeakers. There are silent mode.

哈夫曼树中,树的带权路径长度的含义是各个字符的码长与其出现的此时的乘积和, 也就是电文的代码总长,所以采用哈夫曼树构造的编码是一种能使电文代码总长最短的 不等长编码。-Huffman tree. tree with the right path length is the meaning of the various characters code length of time with the product and, is the message code chief Therefore, the tree structure used Huffman coding can be a code message from the chief of the shortest length coding.
