数字秒表的VHDL语言实现，由于系统定时器8253每秒中断18.2次,利用INT 1AH/00H取得中断次数(DX),得到54.945ms的定时单位。 -Digital stopwatch the VHDL language, because the system timer interrupt 18.2 times per second, 8253, made use of INT 1AH/00H interrupt number (DX), by 54.945ms timing uni

定时器，VHDL 实现，希望对大家有用，共同学习-the timer with vhdl

实现直流电机的控制，增速和减速，用到了定时器(Realize DC motor control, speed up deceleration)
