应用CPLD实现火炮位置测量

阐述丁基于寄存器传输级RTL采集旋转编码器数据来控制电路的一种结构设计方式，选用同步串行接口（SSI）的绝对值格雷码旋转编码器，采用复杂可编程逻辑器件（CPLD），结合图形编程和VerilogHDL硬件等语言编程，通过处理器读取CPLD采集到的旋转编码器的位置数据，实现火炮位置测量；阐述数据主要来源于采集同步脉冲的功能设计与仿真。

Position Measurement of the Artillery through the CPLD

Based on register transfer level RTL pluck rotary, acquisition encoder data, a structured design approach to control the circuit is illustrated. The artillery position measurement is achieved by selection ab-solute rotary encoder of the Gray code of the Synchronous Serial Interface （SSI） , the complex programma-ble logic device （CPLD）, combining graphical programming and some hardware of the language program-ming,such as the verilog HDL,and then the processor reads the rotary encoder position data of the CPLD collected. The data set forth mainly from the function design and simulation of Sync pulse.
