完成的是RS422信号的计数功能，并产生一定的触发信号

运用vhdl硬件描述语言在quartus II开发环境下独立设计与实现了基于精简指令集的五级流水线CPU的设计与实现。该流水CPU包括：取指模块，译码模块，执行模块，访存模块，写回模块，寄存器组模块，控制相关检测模块，Forwarding模块。该CPU在TEC-CA实验平台上运行，并且通过Debugcontroller软件进行单步调试，实验表明，该流水线CPU消除了控制相关、数据相关和结构相关。(Using vhdl hardware description language development environment under quartus II design and implementation of an independent design and implementation of a five-stage pipeline RISC-based CPU' s. The water CPU include: fetch module, decoding module, execution modules, memory access module, the write-back module, the register set of modules, control relevant to the detection module, Forwarding module. The CPU in the TEC-CA experimental platforms, and single-step debugging through Debugcontroller software, experiments show that the pipelined CPU eliminates the control-related, data-related and structurally related.)

AVR IP CORE 可以直接用于工程的开发和 已经通过编译和仿真-AVR IP CORE can be directly used for project development and has passed the compiler and simulation

为了便于信号发射，提高信道利用率、发射功率效率以及改善通信质量，人们研制出各种通信信号的调制样式。尽管调制样式多种多样，但实质上调制不外乎用调制信号去控制载波的某一个（或几个）参数，使这个参数按照调制信号的规律而变化。调制信号可以分别“寄生”在已调信号的振幅、频率和相位中，相应的调制就是调幅、调频和调相这三大类熟知的调制方式。 MSK信号就是调频这一大类中的一种相位连续的移频键控。其主要特点是包络恒定，带外辐射小，实现较简单，可用于移动通信中的数字传输 -see up

本程序设计一个基于FPGA的4相步进电机定位控制系统。由步进电机方向设定电路模块、步进电机步进移动与定位控制模块和编码输出模块构成。前两个模块完成电机旋转方向设定，激磁方式设定和定位角度的换算等工作，后一个模块用于对换算后的角度量编码输出。-This procedure to design an FPGA-based 4-phase stepper motor positioning control system. Direction set by the stepper motor circuit module, stepper motor stepper movement and positioning control module and the code output modules. The first two modules complete the motor rotation direction setting, exciting way of setting the angle and positioning of the conversion work, after a module for the point of view of the volume of converted output encoding.
