The control unit determines an output port of a next router for the input packet. | 12-10-2009 |
20110083134 | APPARATUS AND METHOD FOR MANAGING VIRTUAL PROCESSING UNIT - A method and apparatus for managing a virtual processor including resources for operating application through a real central processing unit, which includes determining a utilization of a plurality of real CPUs to which a plurality of virtual processors are divided to be allocated; and repartitioning the virtual processors and reallocating the repartitioned virtual processor to at least part of the real CPUs, when the utilization of any one of the real CPUs is at a threshold or less. | 04-07-2011 |
20110107344 | MULTI-CORE APPARATUS AND LOAD BALANCING METHOD THEREOF - A multi-core apparatus and method for balancing load in the multi-core apparatus. The multi-core apparatus includes a first core that sends a save request including a context of a task, when a task is switched from an active state to a sleep state, a second core that receives an execution request and executes a task corresponding to the execution request, and a load balancer that receives the save request transmitted by the first core, and sends the execution request to the second core. | 05-05-2011 |
20120060007 | TRAFFIC CONTROL METHOD AND APPARATUS OF MULTIPROCESSOR SYSTEM - A method and apparatus for controlling traffic of multiprocessor system or multi-core system is provided. The traffic control apparatus of a multiprocessor system according to the present invention includes a request handler for processing a traffic request of a first processor, and a Quality of Service (QoS) manager for receiving a QoS guaranty start instruction for a second processor from the multiprocessor system, and for transmitting, when traffic of the second processor is detected, a traffic adjustment signal to the request handler. The request handler adjusts the traffic of the first processor according to the received traffic adjustment signal. The traffic control method and apparatus of the present invention is capable of adjusting the required bandwidths of individual technologies and guaranteeing the real-timeness in the multiprocessor system or multi-core system. | 03-08-2012 |
20120060168 | VIRTUALIZATION SYSTEM AND RESOURCE ALLOCATION METHOD THEREOF - A virtualization system for supporting at least two operating systems and resource allocation method of the virtualization system are provided. The method includes allocating resources to the operating systems, calculating, when one of the operating systems is running, workloads for each operating system, and adjusting resources allocated to the operating systems according to the calculated workloads. The present invention determines the workloads of a plurality of operating systems running in the virtualization system and allocates time resources dynamically according to the variation of the workloads. | 03-08-2012 |
20120075316 | METHOD AND APPARATUS FOR COMPILING AND EXECUTING AN APPLICATION USING VIRTUALIZATION IN A HETEROGENEOUS SYSTEM - A method and apparatus for compiling and executing an application including Central Processing Unit (CPU) source code and Graphic Processing Unit (GPU) source code. The apparatus includes a hardware device including a CPU and a GPU; a compiler that compiles the GPU source code into a GPU virtual instruction; and a hybrid virtualization block that executes an execution file by translating the GPU virtual instruction into GPU machine code. | 03-29-2012 |
20120079498 | METHOD AND APPARATUS FOR DYNAMIC RESOURCE ALLOCATION OF PROCESSING UNITS - A method and apparatus for dynamic resource allocation in a system having at least one processing unit are disclosed. The method of dynamic resource allocation includes receiving information on a task to which resources are allocated and partitioning the task into one or more task parallel units; converting the task into a task block having a polygonal shape according to expected execution times of the task parallel units and dependency between the task parallel units; allocating resources to the task block by placing the task block on a resource allocation plane having a horizontal axis of time and a vertical axis of processing units; and executing the task according to the resource allocation information. Hence, CPU resources and GPU resources in the system can be used in parallel at the same time, increasing overall system efficiency. | 03-29-2012 |
20140156251 | SIMULATION DEVICE AND SIMULATION METHOD THEREFOR - The present invention relates to a simulation method and device. According to the present invention, a simulation method using a plurality of blocks comprises: a dividing step of dividing a simulation into computation operations for performing unique operations on the blocks and communication operations for data exchanges between different blocks; a grouping step of performing a grouping between the interdependent computation and communication operations; and a simulation performing step of performing an operation included in each group using the blocks according to whether or not the level of interdependency between the computation and communication operations is resolved. | 06-05-2014 |
