This paper presents a novel approach for scheduling the IEEE 802.5 token ring. This approach not only guarantees deadlines for synchronous class messages, but also dramatically reduces asynchronous class response times. Further, highly responsive guaranteed service is introduced for alert class asynchronous messages. Conventional use of the IEEE 802.5 token(More)
The research reported in this paper was conducted to identify those attributes, of both sequential circuits and structural, sequential automatic test pattern generation (ATPG) algorithms, which can lead to extremely high test generation times. The retiming transformation is used as a mechanism to create two classes of circuits which present varying degrees(More)
Previous work [15] developed the algorithms, models and methodologies to realize highly responsive, deterministic communications services utilizing the IEEE 802.5 Token Ring Standard. Simulation studies were used to validate the timing determinism property, to demonstrate greatly enhanced asynchronous response limes, and to introduce guaranteed asynchronous(More)
