A method for operatively interconnecting a first and second lighting control subnet is disclosed. In the method, a link claim is transmitted to the first and second lighting control subnets from a bridge. The link claim directs the first and second lighting control subnets to wait for a lighting control command, which is transmitted to the lighting control command to the first lighting control subnet. A random wait time is assigned to the first lighting control subnet and a maximum random wait time is assigned to the second lighting control subnet. Finally, an acknowledgement is received from the first lighting control subnet.

A method and system are disclosed for pre-loading a hard architected state of a next process from a pool of idle processes awaiting execution. When an executing process is interrupted on the processor, a hard architected state, which has been pre-stored in the processor, of a next process is loaded into architected storage locations in the processor. The next process to be executed, and thus its corresponding hard architected state that is pre-stored in the processor, are determined based on priorities assigned to the waiting processes.

The invention provides a node connected island merge based network topology analysis method. In a network topology map, a connected region formed by a node i and adjacent nodes j and k thereof is called as a connected island of the node I, and a minimum node number of the nodes i, j and k included in the island serves as an island number of the connected island. A two-dimensional array data storage structure capable of storing part of intermediate operation results is adopted, so that the method is adaptable to ring network type and tree network connectivity analysis, and is particularly suitable for plant station configuration parallel topology analysis. When the topology analysis method uses a computer multi-core parallel processing technology for achieving plant station bus configuration topology analysis, data collision due to the fact that multiple processors read and write a same node connected island number simultaneously is avoided, topology analysis operational speed is increased, parallel processing efficiency is improved, and operational speed is high while real-time performance is good.

Embodiments of a system are described. This system includes an array of chip modules (CMs) that are configured to communicate data signals with each other via optical communication. In a given CM module, optical signal paths, such as waveguides, are routed in the same way as in the other CMs in the array. In this way, a common optical design in the CMs may be used in the system to prevent data conflicts during the optical communication.

When information of its own station is transmitted to another mobile station by a CSMA access method, by a transmission control method and device, moving speed information and location information is transmitted with a predetermined minimum transmission power until a moving speed of its own station exceeds a first threshold, and the moving speed information and the location information is transmitted with a first transmission power proportional to the moving speed when the moving speed of its own station exceeds the first threshold. In this case, moving direction information of its own station may be acquired and transmitted in addition to the moving speed information and the location information. If the moving speed of the other mobile station exceeds a second threshold higher than the first threshold and a moving direction of the other mobile station is an approaching direction to its own station while its own station is not making transmission with the moving speed of its own station exceeding the first threshold, the first transmission power is switched over to a second transmission power proportional to the moving speed of the other mobile station and the moving speed information and the moving direction information is transmitted.

A method and system are disclosed for saving soft state information, which is non-critical for executing a process in a processor, upon a receipt of a process interrupt by the processor. The soft state is transmitted to a memory associated with the processor via a memory interface. Preferably, the soft state is transmitted within the processor to the memory interface via a scan-chain pathway within the processor, which allows functional data pathways to remain unobstructed by the storage of the soft state. Thereafter, the stored soft state can be restored from memory when the process is again executed.
