URISC 处理器由数据单元和控制单元组成。数据单元中包含保存运算数据和运算结果的数据寄存器，也包括用来完成数据运算的组合逻辑电路单元。控制单元用来产生控制信号序列，以决定何时进行何种数据运算。控制单元要从数据单元得到条件信号，以决定继续进行那些数据运算，数据单元要产生输出信号，数据运算状态等有用信息。-URISC processor by the data unit and control unit. Data unit included in the preservation of data and computing the results of computing the data register, but also data used to complete a combination of computing logic circuit unit. Control unit used to generate the control signal sequence, to determine when and what data computing. Control unit from the data unit received condition signal to determine the continuation of the data computation, data unit to produce output signals, data, such as computing the state of useful information.

    本资源详细的设计了一个FIFO的用法，将数据从ROM中读取送到FIFO缓存中然后RAM从FIFO缓存中读取数据存到内存中，改程序可以很好的学习三者之间的关系

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.
