FPGA

应用背景BCH码是一种流行的用于存储和传输系统中使用的纠错码。它增加了一些冗余检查数据到原始数据帧，冗余数据长度取决于校正能力，和所有计算进行在伽罗华域，适用于FPGA。关键技术编码：线性反馈移位寄存器解码器：1。证算有2×T-1型要求。首先得到奇数阶的。计算时间不一多项式分裂。都有生成多项式和多项式T T特征多项式。接收到的数据分别由T多项式分，上对应于2×T-1电力原始元素综合征，是从1到T。其次，即使顺序综合征的计算奇数的2。误差位置多项式计算误码位置多项式是由无逆的BM算法计算。计算迭代最多2×t-1时刻。定义为综合征的顺序是2×T-1。定义V是错误位置多项式的阶为2×T-1。有一些变量在计算。3.error位置搜索中国搜索的方法来找到错误的位置。每一个元素放在伽罗瓦域为该错误位置多项式，如果其结果等于零，则该元素对应于误差位置。搜索可以进行并行以缩短运行时间。

基于FPGA设计的电子密码锁是一个小型的数字系统，与普通机械锁相比，具有许多独特的优点：保密性好，防盗性强，可以不用钥匙，记住密码即可开锁等。(FPGA-based design of the electronic code lock is a small digital system. It has many unique advantages：good privacy and security , it do not need the key but remember password to unlock, and so on while it compare to ordinary mechanical locks.)

The term web server can refer to either the hardware (the computer) or the software (the computer application) that helps to deliver web content that can be accessed through the Internet.(web server)

说明：  Objects forming possible solution within original problem context are called phenotypes, their encoding, the individuals within the GA, are called genotypes. The representation step specifies the mapping the phenotypes onto a set of genotypes. Candidate solution, phenotype and individual are used to denotes points of the space of possible solutions. This space is called phenotype space. Chromosome, and individual can be used for points in the genotye space. Elements of a chromosome are called genes. A value of a gene is called an allele. Variation Operators The role of variation operators is to create new individuals old ones. Variation operators form the implementation of the elementary steps with the search space.
