fpga VHDL语言，控制DDS产生频率可变的正弦波信号扫频

SoC-Wishbone System IP核的VHDL语言源代码，需要的开发环境是QUARTUS II 6.0。(SoC-Wishbone System IP core VHDL language source code, the need for the development environment is QUARTUS II 6.0.)

说明：  FPGA应用状态机版，适合初学者学习状态机三段式，ASMD图的理解和翻译，以及Verilog语言的应用 最后对仿真的一些理解 其中包含HDL设计及testbench描述 根据要求设计了一个能求出一个32bit字中两个相邻0之间最大间隙的电路。(FPGA application state machine version, suitable for beginners to learn state machine three-stage, ASMD chart understanding and translation, and Verilog language application. Finally, some understanding of simulation, including HDL design and testbench description According to the requirements, a circuit is designed to find the maximum gap between two adjacent zeros in a 32 bit word.)

说明：  串口通信vivado实现，带有仿真文件，可实现数据收发(the uart program based on vivado)

JOP的内核缓存源码，不易找到，大家一定要顶啊-JOP kernel source code cache, not easy to find, we must kits

说明：  数字信号处理的FPGA实现(第4版)的配套源码，极具参考价值。(The source code of the realization of digital signal processing on FPGA (4th edition) is of great reference value.)
