三种16位整数运算器的ALU设计方法
- 三种16位整数运算器的ALU设计方法,调用库函数74181(4位ALU),组成串行16位运算器。(用74181的正逻辑) B.调用库函数74181和74182,组成提前进位16位运算器。(用74181的正逻辑) 注意:调74181库设计,加进位是“0”有效,减借位是“1”有效,所以最高位进位或借位标志寄存器要统一调整到高有效 C.用always @,case方式描述16位运算器。,Three 16-bit integer arithmetic logic unit of the ALU

- 设计要求(黑体小四,1.5倍行距,段前0.5行) 1)密码预先在内部设置,可以设置任意位密码,这里采用6位十进制数字作为密码; 2)密码输入正确后,密码器将启动开启装置。这里密码器只接受前6位密码输入,并以按键音提示,多余位数的密码输入将不起作用; 3)允许密码输入错误的最大次数为三次, 密码错误次数超过三次则进入死锁状态, 并发出警报 4)报警后,内部人员可以通过按键SETUP使密码器回到初始等待状态; 5)密码器具有外接键盘,可以用来输入密码和操作指令; -Desi

Digital-Responder
- 数字抢答器① 用EDA实训仪的I/O设备和PLD芯片实现智能电子抢答器的计。 ② 智能电子抢答器可容纳4组参赛者抢答,每组设一个抢答钮。 ③ 电路具有第一抢答信号的鉴别和锁存功能。在主持人将复位按钮按下后开始抢答,并用EDA实训仪上的八段数码管显示抢答者的序号,同时扬声器发出“嘟嘟”的响声,并维持3秒钟,此时电路自锁,不再接受其他选手的抢答信号。 ④ 设计一个计分电路,每组在开始时设置为100分,抢答后由主持人计分,答对一次加10分,答错一次减10分。 ⑤ 设计一个犯规电路,对提
