<p><P>PROBLEM TO BE SOLVED: To achieve a plurality of items of timer processing by using one hardware timer. <P>SOLUTION: An interrupt setting part 5 equipped with a timer table 21 and an interrupt table 22 capable of storing a counter value and an interrupt value for each kind of software timers, stores a minimum value out of interrupt values stored in the interrupt table 22 in an interval timer match register 12. When an interval timer interrupt occurs, a priority acclimation determining part 15 notifies the fact to an interrupt processing part 6 together with a vector number. Accordingly, the processing part 6 becomes possible to specify the kind of the timer in which the timer interrupt has occurred depending on the vector number, and to achieve the plurality of the items of the timer processing by using only one hardware timer that is an interval time counter 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
