Description: LDPC码是Low Density Parity-check Codes的缩写，一个长为N的LDPC码由它的校验矩阵H来定义，该矩阵的特点是其中的元素0特别多，1特别少——即所谓的“低密度”。一个参数为（N，i，j）的H表示该矩阵中每列有i个1，每行有j个1，矩阵大小为N×K，N代表码字长度，K代表校验子的个数。
-LDPC code is the ab. of Low Density Parity-check Codes. A Length N LDPC is defined by its H matrix. The matrix has many zeros and few ones. which called \"low density\". An H matrix has a parameter as (N,i,j) express that it is the matrix which has i s 1 in each column ,j s one in each row, the size of the matrix is N*K,the N is the code word length ,k is the number of the checks.

Description: OpenGL Blue Book
Introduction:
The OpenGL graphics system is a software interface to graphics hardware. (The GL stands for
Graphics Library.) It allows you to create interactive programs that produce color images of moving
three− dimensional objects. With OpenGL, you can control computer− graphics technology to produce
realistic pictures or ones that depart from reality in imaginative ways. This guide explains how to
program with the OpenGL graphics system to deliver the visual effect you want.

Description: YSS915 (KP2V2) is an LSI for processing Karaoke voice signals.
This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and
key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI
chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that
YSS915 is applicable to various uses.
In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the
surround effect is applied to the movie and music sources for giving the users more enjoyment.

Description: An AHB system is made of masters slaves and interconnections. A general approach to include all possible \"muxed\" implementation of multi layered AHB systems and arbitrated AHB ones can be thought as an acyclic graph where every source node is a master, every destination node is a slave and every internal node is an arbiter there must
be one and only one arc exiting a master and one or more entering a slave (single slave verus multi-slave or arbitrated slave) an arbiter can have as many input and output connections as needed. A bridge is a special node that collapses one or more slave nodes and a master node in a new \"complex\" node.

Description: The field of fuzzy systems and control has been making rapid progress in recent
years. Motivated by the practical success of fuzzy control in consumer products
and industrial process control, there has been an increasing amount of work on
the rigorous theoretical studies of fuzzy systems and fuzzy control. Researchers
are trying to explain why the practical results are good, systematize the existing
approaches, and develop more powerful ones. As a result of these efforts, the whole
picture of fuzzy systems and fuzzy control theory is becoming clearer. Although
there are many books on fuzzy theory, most of them are either research monographs
that concentrate on special topics, or collections of papers, or books on fuzzy mathematics.
We desperately need a real textbook on fuzzy systems and control that
provides the skeleton of the field and summarizes the fundamentals

Description: Due to the unpredictability and complexity properties, chaotic maps are widely applied in security, com- munication, and system control. Existing one-dimensional (1D) chaotic maps can be easily predicted and high-dimensional (HD) ones have more complex structures and higher computation costs. In order to enhance the chaotic performance, this paper proposes a new two-dimensional infinite collapse map (2D- ICM). Compared with existing 2D chaotic maps, 2D-ICM has better ergodicity, hyperchaotic property, un- predictability, and a wider chaotic region. To investigate its application, we further propose an image encryption algorithm using 2D-ICM. Simulation demonstrates that the proposed image encryption algo- rithm has excellent performance for protecting various kinds of images.
