VHDLVERILOG语言实现的CARDBUS的IP源码,已经实现现场应用-CARDBUS IP CORE

DDS信号源设计，有正弦波，方波，三角波，AM波，FM波，还有PSK,FSK,16QAM等多种信号产生。(DDS signal source design, there are sine, square wave, triangle wave, AM wave, FM wave, as well as PSK, FSK, 16QAM and other signal generation.)

如果不考虑占空比，直接利用计数器来进行分频，则占空比会发生变化。下面程序实现1：1的三分频。-if not duty cycle directly counter to the use of sub-frequency, duty cycle will change. Below a program : a third of the frequency.

这是Xilinx ISE 14.X以及vivado、vivado_hls的license，亲测可用(Xilinx ISE 14.x vivado, vivado_hls license, pro-test available)

三相电流滞环跟踪PWM逆变器。逆变电路负载电流与指令电流比较产生PWM波形。经验证可很好实现功能。(The three-phase hysteresis current tracking PWM inverter. Load current command current of the inverter circuit generating a PWM waveform. Proven functions well.)
