自适应均衡器

运用quartus 软件模拟的电子琴，实现按键出现不同音调的音乐。(Quartus software simulation using keyboard, keys appear to achieve different tones of music.)

数控分频器设计:对于一个加法计数器，装载不同的计数初始值时，会有不同频率的溢出输出信号。计数器溢出时，输出‘1’电平，同时溢出时的‘1’电平反馈给计数器的输入端作为装载信号；否则输出‘0’电平。 -NC divider design : an adder counter, loading the initial count value, have different frequency output signal of the overflow. Counter overflow, the output"1 "Level, Overflow at the same time the"1 "level feedback to the counter input signal as loading; Otherwise output"0 "level.

利用VHDL语言编写的一个crc功能模块，可下载到FPGA实现功能-use VHDL to prepare a crc function of the module, which can be downloaded to the FPGA functions

system c 是在C环境下的硬件描述语言,比VHDL 等语言具有更强的抽象能力,内有system C的开发支持库和一些VC下的开发例程-system in the C environment hardware description language, than languages such as VHDL is more abstract, C within a system to support the development of the VC and some routines under development

说明：  altera fpga 实现fft，用fft IP核，有matlab仿真代码(Altera FPGA implementation of FFT, FFT IP core, matlab simulation code)

i2c配置SAA7113，非常有用的程序，做视频采集类必看(i2c configure SAA7113)

This is code of UVM CALLBACK function.
