电话计费器程序/*信号定义:
clk: 时钟信号,本例中其频率值为1Hz;
decide: 电话局反馈回来的信号,代表话务种类,“01”表示市话,“10”表示
长话,“11”表示特话;
dispmoney: 用来显示卡内余额,其单位为角,这里假定能显示的最大数额为50 元
(500 角);
disptime: 显示本次通话的时长;
write,read: 当write 信号下降沿到来时写卡,当话卡插入,read 信号变高时读卡;
warn: 余额过少时的告警信号。本例中,当打市话时,余额少于3 角,打长
话时,余额少于6 角,即会产生告警信号;
cut: 当告警时间过长时自动切断通话信号。 */-telephone billing for procedures/* signal definition : clk : clock signal, which in this case, their frequency of 1Hz; decide : Telephone Bureau feedback signal, then the Treasury representative types, "01" Urban said, "10" The point said, "11" expressed special words; dispmoney : to show the card balance, the unit of angle, Here are supposed to show the maximum amount of 50 billion yuan (500 angle); disptime : The calls show the length; write, read : When the write signal arrival of the down time to write cards, When the card insert, read signal change high Reader; warn : Fees balance of the alarm signal.
