Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI Encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check for bit unstuffing errors]. Otherwise complete and fully functional. There is currently no test bench available. This core is very simple and is proven in hardware. I see no point of writing a test bench at this time.

摘 要 文章以空间监控系统为背景,深入研究了JPEG图像压缩标准的实现方法,并基于FPGA对其进行了实现和优化。文中给出了详细的实现方法和优化过程,测试表明达到了很好的效果。 简单介绍了有损静态图像压缩当前有两种比较流行的标准JPEG和JPEG2000。说明了用JPEG方法压缩的原因。 介绍JPEG基本原理：JPEG对灰度图像的压缩处理过程主要包括:图像分割,离散余弦变换(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脉冲编码调制(Differential Pulse Code Modulation,DPCM)对直流系数(DC),行程长度编码(Run-Length Encoding,RLE)对交流系数(AC),霍夫曼(Huffman)编码等。 JPEG标准的特点是离散余弦变换。 比较详细介绍压缩系统的构成和实现。实现提及步骤， JPEG压缩模块设计和编码模块实现细节。

) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for Encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.

3 Dimensions TV (3DTV) became commercially available in the United States in 2010 and service in other countries was expected to follow soon thereafter. 3DTV is a subset of a larger discipline known as 3D Video (3DV). There are now many routine vendor announcements related to 3DTV/3DV, and there are also conferences wholly dedicated to the topic.

The very title of this book is borrowed from the information theory vocabulary, and, quite naturally, it is an outline of this theory that will serve as an introduction. The subject of information theory is the scientific study of communications. To this end it defines a quantitative measurement of the communicated content, i.e. informa- tion, and deals with two operations essential for communication techniques: source coding and channel Encoding.
