10004 results about "Computer architecture" patented technology

In computer engineering, computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. Some definitions of architecture define it as describing the capabilities and programming model of a computer but not a particular implementation. In other definitions computer architecture involves instruction set architecture design, microarchitecture design, logic design, and implementation.

Method and apparatus for data hierarchy maintenance in a system for mask description

A method and apparatus for performing an operation on hierarchically described integrated circuit layouts such that the original hierarchy of the layout is maintained is provided. The method comprises providing a hierarchically described layout as a first input and providing a particular set of operating criteria corresponding to the operation to be performed as a second input. The mask operation, which may include operations such as OPC and logical operations such as NOT and OR, is then performed on the layout in accordance with the particular set of operating criteria. A first program data comprising hierarchically configured correction data corresponding to the hierarchically described layout is then generated in response to the layout operation such that if the first program data were applied to the flattened layout an output comprising data representative of the result of performing the operation on the layout would be generated. As the first program data is maintained in a true hierarchical format, layouts which are operated upon in accordance with this method are able to be processed through conventional design rule checkers. Further, this method is capable of being applied to all types of layouts including light and dark field designs and phase shifting layouts.

Energy-saving method of cloud data center based on virtual machine migration and load perception integration

The invention relates to a system level virtualization technology and an energy-saving technology in the field of the structure of a computer system, and discloses an energy-saving method of a cloud data center based on virtual machine migration and load perception integration. The method comprises the steps: dynamically completing the migration and the reintegration of the load of a virtual machine in the cloud data center by monitoring the resource utilization rate of a physical machine and the virtual machine and the resource use condition of current each physical server under the uniform coordination and control of an optimized integration strategy management module of the load perception and an on-line migration control module of the virtual machine, and tuning off the physical servers which run without the load, so that the total use ratio of the server resource is improved, and the aim of energy saving is achieved. The energy-saving method of the cloud data center based on the virtual machine on-line migration and the load perception integration technology is effectively realized, the amount of the physical servers which are actually demanded by the cloud data center is reduced, and the green energy saving is realized.
