它是一种以地址总线数据总线为结构的8位微处理器，主要由两部分组成：一是控制单元，数据通路控制单元控制微处理器的所有块、寄存器和部件，数据通路由地址和数据通路信号处理组成指令读写加法；

FIR滤波器的verilog HDL代码示例，以16阶为例(Verilog HDL code for fir filter)

adder_array的设计。加法器阵列设计，顶层模块，四步流水，21位(adder_array the design. The adder array design, top-level module, four-step pipeline, 21)

本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)

总结设计中的重点及注意的地方，常出现错误的地方等。-Summarize the design of the focus and attention of local, often the wrong place and so on.
