Abstract

From practice of engineer,this article introduces real-time interrupt processing based on technology of KernelPlugIn and DDK,and realizes the working machenism of high resolution timed interrupt and analyses the relation of Windows 2000 working timer and interrupt timer.To use PC′s system timer and parallel port of current hardware resource to change the interrupt period modifying the system timer value of fractional frequency,and change the output of parallel port voltage by the flag of variable to see the result using the scope,according the examination to write the sheet and frondose data of interrupt period.
