VHDl硬件描述语言实现单片机与cpld通信-VHDL hardware description language to achieve communication between SCM and CPLD

As you have learnt that sleep( )/usleep()/nanosleep() are not good to delay a process. Timers can provide more accurate time control in applications. In this lab, you will explore POSIX timers and signal programming, experience the timer drift. The primary focus of this lab will be "time". The experiment will show you several methods to measure time in your applications.
