键盘接口电路的一个工程

多进制数字频率调制(MFSK)系统VHDL程序-Multi-band digital frequency modulation (MFSK) system VHDL procedures

采用Verilog HDL设计,在掌宇智能开发板上得到实现 根据抢答器的原理，整个电路可划分为三部分：采样电路、门控电路和译码电路- Uses Verilog the HDL design, obtains the realization basis on the palm space intelligence development board to snatch the answering principle, the entire electric circuit may divide is three parts: The sampling electric circuit, the gate control the electric circuit and the decoding circuit

说明：  实现24小时计时，因为位数不够，这里是12进位，可自行调整进位数(Realize 24-hour timing, because the number of digits is not enough, here is 12 carry, you can adjust the carry number by yourself.)

QPSK在赖斯信道下的模拟仿真，包括K=6和K=10下的情况(QPSK in, Laisi Xin Road, under the simulation, including the case of K = 6 and K = 10 under)

VHDL数字系统设计和工程实践1，包含原理，真值表和原理图，以及VHDL源代码.-VHDL digital system design and engineering practice, one that contains principles, truth table and schematic, as well as VHDL source code.

VHDL在SOURCEINSIGHT的插件-VHDL in SOURCEINSIGHT plug-ins

Multipleksor 3 to 1 - 3x1bit in, 1x1bit out

详细讲述TURBO码的FPGA实现原理，可作参考，不是码源(A detailed account of the FPGA implementation of principle of the TURBO code can be used as reference, not source code)

说明：  用verilog实现除法器，调用了ip核，不仅有源代码，还有测试程序的时序编写(verilog ise divider)

说明：  Xilinx原语的使用介绍，特别全面，希望对大家有所帮助，(Introduction to the use of Xilinx primitives, particularly comprehensive,I hope it will be helpful to you all.)
