Civil air defense workРРCounty continuation records has examined and approved the draft, spirit, believe, comprehensive Yearbook of zhuanglang already prepared draft, entered the phase of evaluation. Civil air defense workР置各控制信号如下:РH12РH11РH10РH9РH4РX0РX1РERAРRA-OРMР0Р1Р0Р0Р0Р按脉冲单元中的PLS1脉冲按键,在RACK上产生一个上升沿,使通用存放器中的值左移。因进位存放器CY的初始值为0,在RACK脉冲作用下将CY打入通用存放器的最低位Q0。同时在RACK脉冲作用下把通用存放器的最高位Q7〔为1〕打入进位存放器CY,使CY灯亮,这样就实现了带进位的左移功能。Р同样置各控制信号如下,并且按脉冲单元中的PLS1脉冲按键,可实现带进位的右移功能。РH12РH11РH10РH9РH4РX0РX1РERAРRA-OРMР0Р1Р0Р0Р0Р???РРРР五、总结Р通过这次实验,我了解了通用存放器的判零电路,实现了用进位存放器来实现带进位的左移、右移,熟悉了带进位位控制算术逻辑运算器的组成和硬件电路。实验过程中遇到了一些问题,在老师和同学的帮助下得到了解决,成功的完成了本次实验。
