Abstract
A computer system provides for the use of isochronous interrupts by devices coupled with the system. Isochronous interrupt requests are received by an interrupt controller during a first time period, recorded, and executed during a second time period. The devices are equipped to handle the delay in interrupt execution. The interrupt controller is set to service isochronous interrupts on a periodic basis. The interrupt controller may flexibly schedule the execution of the isochronous interrupt request at any time during the second time period.
