    • A high performance wrapper circuit for a GALS(Globally Asynchronous Locally Synchronous System) is provided to reduce power consumption by operating a clock only when the data is required. A delay clock generator(30) generates a clock operating a small locally synchronous module. A receiver port(20) receives a request signal according an enable signal of the small locally synchronous module and outputs a first clock stop control signal selectively according to the reception state of the enable signal before transmitting a response signal corresponding to the request signal. A sender port(10) selectively outputs a second clock stop control signal according to the reception state of the enable signal before receiving the response signal corresponding to the request signal according to the enable signal of the small locally synchronous module. A first latch(41) latches the data inputted by the data of the receiver port and transmits the data to a LS(Locally synchronous) modules.

    • A high-availability cluster system having a hierarchical multi-backup structure and a method for implementing high availability using the same are provided to offer an efficient availability by improving low availability and long error recovery time. A high-availability cluster system having a hierarchical multi-backup structure comprises a main node(100), a sub node(200), and backup nodes(300-1-300-N). The main node, as an active node, provides services to the nodes of a configured client membership, and outputs its own operation state information. The sub node, the backup node of the main node, receives and outputs a service provided from the main node, monitors whether a fault is generated from the main node, and outputs its own operation state information. Each of the backup nodes receives a service which is outputted through the sub node from the main node, and monitors whether a fault is generated from the sub node.
