This paper explores the use of the IEEE 802.11 Frame Check Sequence as a source of pseudo-random numbers for use when deciding whether to sample a packet. This theory is tested by analysingthe distribution of Frame Check Sequences from a large, real world capture. Finally, a BPF program ...
2、伪随机码(Pseudo Random Code)又称为伪噪声码(Pseudo Noise Code),简称PN码。简单地说,伪随机码是一种具有类似白噪声性质的码。白噪声是一种随机过程,它的瞬时值服从正态分布,功率谱在很宽的频带内都是均匀的。白噪声具有优良的相关特性,但至今无法实现对其进行放大、调制、检测、同步及控制等操作。在工程上...
$random - Return a random value. Program Language Interface (PLI) The PLI provides a programmer with a mechanism to transfer control from Verilog to a program function written in C language. It is officially deprecated by IEEE Std 1364-2005 in favor of the newer Verilog Procedural Interface, ...

These functions are similar to the IEEE1364 standard $random functions, but they use the Mersenne Twister (MT19937) algorithm. This is considered an excellent random number generator, but does not generate the same sequence as the standardized $random.Built...
Block RAMs (or BRAM) stands for Block Random Access Memory.Block RAMs are used for storing large amounts of data efficiently inside of your FPGA like images or video, for high-performance state machines or FIFO buffer, for learge shift registers, lar...
