    • A key engine that performs route lookups for a plurality of keys may include a data processing portion configured to process one data item at a time and to request data when needed. A buffer may be configured to store a partial result from the data processing portion. A controller may be configured to load the partial result from the data processing portion into the buffer. The controller also may be configured to input another data item into the data processing portion for processing while requested data is obtained for a prior data item. A number of these key engines may be used by a routing unit to perform a large number of route lookups at the same time.
    • 执行多个键的路线查找的关键引擎可以包括被配置为一次处理一个数据项并在需要时请求数据的数据处理部分。 可以将缓冲器配置为存储来自数据处理部分的部分结果。 控制器可以被配置为将来自数据处理部分的部分结果加载到缓冲器中。 控制器还可以被配置为在对于先前的数据项获得所请求的数据的同时,将另一数据项输入数据处理部分进行处理。 路由单元可以使用许多这些密钥引擎来同时执行大量的路由查找。

    • A bit coding method modifies the bit-steam information in such a way as to provide a very high compression during lossless symbol coding and may be used as a preprocessor for Huffman and arithmetic encodings or on its own. A bit rearrangement scheme (BRS) improves the run length within a data symbol set and achieves a more efficient data-to-symbol mapping. The BRS is implemented on the data symbol set in a column-by-column fashion. The BRS can be combined with any available lossless coding scheme, providing for a more efficient lossless bit coding scheme (ALBCS).
    • 位编码方法以无损符号编码的方式修改比特 - 蒸汽信息,以提供非常高的压缩,并且可以用作霍夫曼和算术编码的预处理器或其自身的编码。 比特重排方案(BRS)改进了数据符号集中的运行长度,并实现了更有效的数据到符号映射。 BRS是以逐列方式在数据符号集上实现的。 BRS可以与任何可用的无损编码方案组合,从而提供更有效的无损位编码方案(ALBCS)。

    • In many instances it is necessary to store and transfer information and data on a temporary basis. Typically this information and data is transient but is vulnerable to capture and piracy as it is not in an encrypted state. Therefore a unique method is disclosed that performs randomized scrambling of unprotected digital information that make it unreadable, or otherwise unusable, without the appropriate descrambling. In order to be effective and secure the method requires a large population of scrambling patterns, or codes, and assigns them index numbers. Scrambling patterns are randomly chosen for use in the scrambling of the information and data. Unique schemes for developing this large population of patterns and choosing at random the usable set at each interval or usage. In particular the method is useful in the protection of digital content.
    • 在许多情况下,有必要临时存储和传输信息和数据。 通常,这些信息和数据是短暂的,但是由于它不处于加密状态,因此易受捕获和盗版的攻击。 因此,公开了一种独特的方法,其进行无保护的数字信息的随机加扰,使得其不可读或者不可用,而无需适当的解扰。 为了有效和安全,该方法需要大量的加扰模式或代码,并分配它们的索引号。 随机选择加扰模式用于信息和数据的加扰。 用于开发这种大量模式的独特方案,并在每个间隔或使用情况下随机选择可用集合。 特别地,该方法在数字内容的保护中是有用的。
