8255参考设计VHDL源代码

VHDL tutorial for beginning learner

本程序利用VHDL实现二维离散余弦变换，经本人测试，在Quartus II7.0软件上可正确仿真，希望大家积极采纳

本源代码是RS（31,19）编码器的顶端实现程序和测试程序，此程序可以验证编码器工作与否。此代码，已在ModelSim验证通过。并附上测试时所产生的结果图像。(Source code is RS (31,19) encoder to achieve the top programs and testing procedures, this program can verify the encoder to work or not. This code has been verified in ModelSim. Together with the result when the test images.)

FPGA控制AG9226进行采样的代码,并用signaltap测试了一下其正确性(FPGA control AG9226 to sample the code, and use signaltap to test the correctness of the demo.)

VHDL开发的计数器。源程序不复杂，应该都能看懂。最重要的注意：是时序问题-VHDL development of the counter. Source code is not complicated, should be able to understand. The most important Note : Timing is the issue

用blockram实现移位寄存器，开发语言为verilog hdl(Shift register with blockram achieve the development language for the verilog hdl)

利用ANSYS有限元仿真软件对复合材料进行异常检测仿真实验，程序为一损伤样板模型(ANSYS finite element simulation software for composites simulation anomaly detection, the program is a damage model model)

说明：  设计了六相感应电机的控还原 制平台的硬件结构及其各个组成部分,控制平台结构主要由DSP控制系统和主驱动电路系统以及检测电路系统组成。控制系统采用TI公司的TMS320F2812快速DSP控制芯片。 (This paper designs the hardware structure of the six-phase motor control system and introduces every component. The control platform consists of DSP control system, main drive circuit system and detection circuit system .The control system adopts TMS320F2812 DSP chip of TI Company. 更多还原 )

verilog，FPGA的TDC电路设计(verilog ，TDC base on FPGA)

DEMO中完成WIAGAND26/32的（EMP7128实现）协议程序源代码-DEMO completed WIAGAND26/32 (EMP achieved) agreement procedure source code
