The paper proposes the architecture of an IEEE1394 device driver that supports the priority based queueing of packets and reduces the interrupt latency time in ISR (Interrupt Service Routine), thereby guaranteeing device driver level support for real time characteristics and improving the predictability of high priority applications. This architecture can accommodate the real time requirements of various applications and services such as digital multimedia services with QoS guarantees, hard real time instrumentation and control applications, and the implementation of real time middleware in home networks.
