讲述软解调很不错的一片文档，主要阐述的是8PSK的软解调FPGA实现，但对8PSK的软解调原理阐述很清楚，没有多余的东西，但需要注意其中各个调制符号点得顺序。(About soft demodulation of a document is very good, mainly on the soft 8PSK demodulation FPGA, but soft 8PSK demodulation principle describes very clearly, no extra stuff, but need to pay attention to the point where each modulation symbol was in order.)

SDRAM即同步动态随机存储器，同步是指 Memory工作需要同步时钟，内部的命令的发送与数据的传输都以它为基准；动态是指存储阵列需要不断的刷新来保证数据不丢失；随机是指数据不是线性依次存储，而是自由指定地址进行数据读写。因为SDRAM具有存取速度大大高于FLASH存储器, 且具有读/写的属性, 因此SDRAM在系统中主要用于程序的运行空间,大数据的存储及堆栈。SDRAM是高速的动态随机存取存储器, 它的同步接口和完全流水线的内部结构使其拥有极大的数据速率, SDRAM的时钟频率可以达到100Mhz以上, 一片16位数据宽度的SDRAM的读写数据带宽达到1.6Gbit/s。

An universal shift register performs the following tasks load, right shift ,left shift and parallel load as the selection inputs are 00,01,10,11 respectively. Such a register is implemented here in Quartus.
