SDRAM驱动程序

vhdl cpu芯片逻辑设计的一部分实现 只有一小部分 大家可以看一下 寄存器 加法器之类的(vhdl cpu chip logic design part of its implementation only a little part everry look and see b=about registers adder and so on)

黑金FPGA助学版-tcl,包含开发板所有管脚。不需要再对板子管脚定义。AX301(Black Gold FPGA Student Edition-tcl, development board contains all the pins. No need for a board pin definitions. AX301)

此为实现第14.7.9章所需的激励文件 该代码为门级RTL描述。(Stimulus file to verify Section 14.7.9 the functionality of gate vs. RTL description.)

说明：  Verilog实现按键消抖，工程，已下板验证通过。(Verilog achieves keystroke jitter elimination. The project has been validated on the lower board.)

verilog vga 图像处理(verilog vga)

HDLC通信协议，FPGA实现，包含源文件和仿真测试文件。(HDLC comunication)

对于已获得的脉冲包络采样序列，需测量的脉冲特征参数主要有：脉冲幅值(PA)、脉冲到达时间(TOA)和脉冲宽度(PW)。实际测量中，脉冲波形的形状是各种各样的，但其主要的参数有脉冲幅度、脉冲宽度、脉冲周期、脉冲占空比、脉冲前沿(上升时间)、脉冲后沿(下降时间)、脉冲上冲、脉冲下冲、脉冲下垂、脉冲顶部不平度等，脉冲参数的计量主要就是对这些参数进行计量。本程序包实现基于FPGA实现脉冲宽度和重复周期的测量。(Who have access to the pulse envelope sample sequence, the pulse measurement to be the main characteristic parameters are: pulse amplitude (PA), pulse time of arrival (TOA) and pulse width (PW). The actual measurement, the pulse shape is a wide variety of shapes, but its main parameters of the pulse amplitude, pulse width, pulse period, pulse duty cycle, pulse leading edge (rise time), pulse along (down time), the red pulse, pulse undershoot, pulse droop, pulse irregularities, such as at the top, the measurement of pulse parameters is mainly the measurement of these parameters. The package FPGA-based pulse width and repetition to achieve the measurement cycle.)
