Vhdl 语言和语言执行 dds 和 fft
DDS 波形发生器的核心组件是蓄能器。蓄能器是一个正在运行的计数器，将值存储到当前阶段生成波形。蓄能器更新和累加器增量值确定生成波形的频率速率。如果蓄能器每秒和累加器增量更新 360 倍的例子是一个学位，然后生成的频率是 1 Hz （每秒 360 度）。当蓄能器相位值达到最大 （360 度） 它滑过和 0 度时再次启动。为了更准确地代表相位值蓄能器通常使用 32、 48 或 64 位计数器。在 32 位累加器的阶段值具有一个范围从 0 到 4294967295，代表的参考波形或 0 到 360 度的一个完整周期。
累加器 (阶段) 的当前值用于参考波形来确定下一个输出值的查找表中执行查找操作。查找表包含一个周期的波形生成，通常包含 1024年到 8192 采样点所代表的波形。
因为累加器的值通常有很多决议比参考波形，由样本，数目有限的查找操作也可以执行两个样本中的参考波形之间的内插。这基于累加器的值在额外的分辨率进行并返回生成的信号中一个更准确的更新值，提供了更好的频率控制和较少的谐波失真。

The sample demo workspace includes two projects: DIB Test for Win32 environments, and DIB CE for CE environments that demonstrate the DIB wrapper. You will need the CE SDKs from Microsoft to be installed before you can build DIBSectionTestCE.dsw. There is also a version of the DIBSection wrapper ported by Kenny Goers with no dependancies on MFC. This version is currently slightly out of sync with the MFC version, and is provided as a convenience only. -The sample demo workspace includes two projects: DIB Test for Win32 environments, and DIB CE for CE environments that demonstrate the DIB wrapper.

写出来的旅馆管理系统虽然还很粗糙,也不是很稳定,但是它也算是我学了这么久计算机一点小小的成就吧,也许显得有点可笑,但是偶尔得看到它也能让自己感到有一点点的满足,并不是什么都没学到,把它贴在这也是希望能有高手可以给我指点啊-Written by the hotel management system, although very rough, not very stable, but it can also be considered for such a long time I studied computer achieved a little bit, maybe it sounds a bit ridiculous, but occasionally get to see it they can feel a little bit of satisfaction, is not nothing to learn, it is also posted on the hope that you can give me advice ah
