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 文章以空間監(jiān)控系統(tǒng)為背景,深入研究了JPEG圖像壓縮標(biāo)準(zhǔn)的實(shí)現(xiàn)方法,并基于FPGA對(duì)其進(jìn)行了實(shí)現(xiàn)和優(yōu)化。文中給出了詳細(xì)的實(shí)現(xiàn)方法和優(yōu)化過(guò)程,測(cè)試表明達(dá)到了很好的效果。 簡(jiǎn)單介紹了有損靜態(tài)圖像壓縮當(dāng)前有兩種比較流行的標(biāo)準(zhǔn)JPEG和JPEG2000。說(shuō)明了用JPEG方法壓縮的原因。 介紹JPEG基本原理：JPEG對(duì)灰度圖像的壓縮處理過(guò)程主要包括:圖像分割,離散余弦變換(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脈沖編碼調(diào)制(Differential Pulse Code Modulation,DPCM)對(duì)直流系數(shù)(DC),行程長(zhǎng)度編碼(Run-Length Encoding,RLE)對(duì)交流系數(shù)(AC),霍夫曼(Huffman)編碼等。 JPEG標(biāo)準(zhǔn)的特點(diǎn)是離散余弦變換。 比較詳細(xì)介紹壓縮系統(tǒng)的構(gòu)成和實(shí)現(xiàn)。實(shí)現(xiàn)提及步驟， JPEG壓縮模塊設(shè)計(jì)和編碼模塊實(shí)現(xiàn)細(xì)節(jié)。

) 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.
