Description: NOR和NAND是现在市场上两种主要的非易失闪存技术。Intel于1988年首先开发出NOR flash技术，彻底改变了原先由EPROM和EEPROM一统天下的局面。紧接着，1989年，东芝公司发表了NAND flash结构，强调降低每比特的成本，更高的性能，并且象磁盘一样可以通过接口轻松升级。但是经过了十多年之后，仍然有相当多的硬件工程师分不清NOR和NAND闪存。-NOR and NAND market is now two main types of non-volatile flash memory technology. Intel in 1988 developed the first NOR flash technology, completely changed the original from EPROM and EEPROM dominated situation. Then, in 1989, Toshiba made a NAND flash structure, emphasis on reducing the cost per bit, higher performance, and as the disk can easily upgrade through the interface. But after more than a decade later, there is still a considerable number of hardware engineers distinguish NOR and NAND flash memory.

Description: ASN．1（Abstract Syntax Notation One）是由ITU－T制定的，符合以上三点要求。它定义的编码规则（如BER、PER）就相当于从局部语法到传送语法之间的转换规则。目前，很多网络协议的消息格式都是用ASN．1句法描述的，并指明了采用何种编码规则。在协议的具体实现时，我们必须在发送方设置一个ASN．1编码器，将发送方所要传送的消息经ASN．1编码后再发送出去；然后在接收方设置一个ASN．1解码器，将接收到的经ASN．1编码的消息解码为符合接收方局部语法的消息格式。由于ASN．1已经成为国际化的标准，这样，经ASN．1处理的信息独立于任何应用环境，就不会因为应用环境的不同而引起二义性的解释。
ITU－T专门讲述ASN．1的共有20个协议：X．680～X．699（还不包括较老的X．208和X.209），内容相当丰富，也非常复杂。本文的任务不在于讲述ASN．1规定的诸多名词和冗长繁杂的编码细节，而只是对BER和PER的要点做简要介绍，并将它们对比起来进行研究-ASN. 1 (Abstract Syntax Notation One) by the ITU-T developed, consistent with the above three requirements. It defined coding rules (such as BER, PER) from the local grammar equivalent of transmission conversion between the grammar rules. At present, many of the news network protocol format is used ASN. A description of the syntax and specify what the coding rules. The agreement is a concrete realization, we must set up a sender ASN. An encoder, the sender will have to transmit information via the ASN. After a code sent; The receiver then set up an ASN. A decoder that will receive by the ASN. A coding information for decoding receiver with the local news format syntax. As ASN. One has become international standards, so that by ASN.

Description: Objective Systems Open H.323 for C (ooh323c) is a simple H.323 protocol stack developed in C. The ASN.1 PER messaging code was developed using the ASN1C compiler using a modified version of our core run-time libraries. Additional open source components as well as code developed in-house were added to produce a functioning stack.

Description: The Volume Fog sample shows the per-pixel density volumetric rendering
technique. The fog volume is modeled as a polygonal mesh, and the
density of the fog at every pixel is computed by subtracting the front
side of the fog volume from the back side. The fog is mixed with the
scene by accumulating an in/out test at every pixel -- that is, back-facing
fog polygons will add, while front-facing ones will subtract. If the value
is non zero, then the scene intersects the fog and the scene s depth value
is used. In order to get better results, this demo uses 12 bits of precision
by encoding high and low bits in different color channels. -The Volume Fog sample shows the per-pixel density volumetric rendering technique.
