  • Method of executing concurrent tasks by a subsystem managed by a central processor
    Patent number: 7797700
    Abstract: Systems and methods are provided for processing different concurrent tasks by a subsystem managed by a central processor. Each tasks is comprised of successive messages including a first message, intermediate messages, and a last message. Each intermediate message comprises a subtask parameter and a link to the next message that indicates the time when the next message is to be processed. The central processor and the subsystem are connected to a storage memory and several counters associated with respective tasks. The system and method reduce task disruptions of the system.
