用VHDL语言写的，音乐演奏程序，范例歌曲为“青花瓷”片段。...

可以实现DDC各个模块的功能，如内插、抽取、FIR滤波等功能(DDC can realize the function of each module, such as interpolation, extraction, FIR filtering)

PLL 锁相环verilog程序 可以直接使用(The PLL can be used directly good use)

初学ＶＨＤＬ有用的，了解后对复杂设计有很大帮助．-VHDL beginner useful understanding of the complexity of the design has been inspired by them.

关于vhdl对硬件接口8237的编程，可以在进行fpga/cpld设计是作为模块用到-VHDL for the hardware interface on the 8237 programming, you can carrying out fpga/cpld design is used as a module

This application note explains the process of eveloping and debugging a hardware abstraction layer (HAL) software device driver, to aid device driver development for the HAL of the Altera Nios® II system. The various software development stages are illustrated using the Altera_Avalon_UART as an example hardware device, and an example of a HAL software device driver called my_uart.-This application note explains the process of eveloping and debugging a hardware abstraction layer (HAL) software device driver, to aid device driver development for the HAL of the Altera Nios® II system.
