20100005433 | CIRCUIT DESIGN APPARATUS AND CIRCUIT DESIGN METHOD - A circuit design apparatus for designing an LSI including a memory circuit for storing data and an error protection circuit for performing an error protection over the data stored in the memory circuit on the basis of design information, the circuit design apparatus includes: an extracting unit for extracting information of configuration of the memory circuit with error protection circuit from the design information; and a circuit arrangement controller for determining whether to insert a check circuit for supplying a check signal into the memory circuit to verify the error protection circuit on the configuration information. | 01-07-2010 |
20100061376 | SHARED MEMORY SYSTEM - A shared memory system including: a shared memory includes a plurality of memory banks; a plurality of input ports; a plurality of input buffers; and a controller for controlling writing-into and reading out of the shared memory and for transferring data from each of the input buffers to the shared memory, wherein when one of the memory banks is cycled back next to the starting memory bank, another memory block is to be selected next for writing the remainder of a series of data, said controller controlling each of the input buffers to transfer a plurality of series of data to the shared memory successively with a time gap while switching to said another memory block, said controller offsetting a start memory bank in said another block for start writing the remainder of the series of data by an amount of memory banks corresponding to the time gap. | 03-11-2010 |
20100316053 | ADDRESS LEARNING METHOD AND ADDRESS LEARNING SWITCH - A switch operating in a multistage switch network is provided. The switch includes a plurality of ports, a first processor for processing a source address and a destination address of a packet received by the plurality of ports, and a second processor for including a memory storing data of the packet, and for outputting, under the control of the first processor, the data of the packet stored on the memory, wherein the first processor calculates a hash value of the source addresses of the packet in accordance with a specific hash function, identifies a output port connected to a switch that corresponds to the hash value and is to learn the source address, and causes the second processor to output the data of the packet to the output port. | 12-16-2010 |
20100316057 | Relay device suppressing frame flooding - In a relay device, a first memory stores correspondence information representing a correspondence relationship between a node and a port. A second memory stores information by which a port to suppress flooding of a frame is distinguishable. A relay part limits a port, which floods a frame addressed to a node of which information is not stored in the first memory, based on the information stored in the second memory. | 12-16-2010 |
20110040849 | RELAY DEVICE, MAC ADDRESS SEARCH METHOD - A relay device includes: memories, each memory being operable to store at least a data pair formed of a MAC address and a port number; a search unit to search only amongst ones of the memories having valid data pairs when searching for a port number based upon a MAC address; a data moving unit to move valid data pairs to different locations within the plurality of memories in order to reduce a total number of memories, amongst the plurality thereof, having valid data pairs; and a power supply controller to selectively stop supplying power to ones of the memories storing only invalid data. | 02-17-2011 |
20120011236 | SERVER MANAGEMENT APPARATUS AND SERVER MANAGEMENT METHOD - A computer is communicable with a managed server having a network boot function. The computer refers, when the managed server starts network boot, to data stored in a storage unit which stores status management data and status-program connection data. The status management data specifies an operation status into which the managed server is to be shifted when the managed server has been network booted. The status-program connection data indicates a program for shifting the managed server into the specified operation status. The computer determines, on the basis of the status management data and the status-program connection data, a program to be executed during the network boot to shift the managed server into the specified operation status. The computer notifies the managed server of information necessary for loading the determined program. | 01-12-2012 |
20130042120 | CONTROL APPARATUS AND METHOD - A disclosed control apparatus includes: a first data storage unit storing data representing whether transition to an energy-saving state is prohibited, for each of memory blocks in a memory device, wherein power control is carried out for each of the memory blocks; a second data storage unit storing the number of times that access to a memory block that is in the energy-saving state is requested, for each of threads of a program; and a first controller that increments the number of times of a requesting source thread of a memory request, upon detecting a memory block including an access destination of the memory request received from a processing unit is in the energy-saving state, and sets data representing the transition to the energy-saving state is prohibited for the memory block including the access destination of the memory request upon detecting the number of times after incrementing exceeds a threshold. | 02-14-2013 |
20130046943 | STORAGE CONTROL SYSTEM AND METHOD, AND REPLACING SYSTEM AND METHOD - A row buffer | 02-21-2013 |
20140047125 | APPARATUS AND METHOD FOR CONTROLLING VIRTUAL SWITCHES - An apparatus includes a controller, a converter, and table information storing physical identification information identifying a physical port of first and second physical switches in association with virtual identification information identifying a virtual port of a virtual switch. For each virtual switch, the controller outputs control information determined based on a predetermined protocol and manages the received control information. The converter, based on the table information, converts the physical identification information added to the received control information and identifying a physical port via which the first physical switch has received the control information, into the associated virtual identification information, converts the virtual identification information added to the control information outputted from the controller and identifying a virtual port via which the control information is to be transmitted, into the associated physical identification information, and relays the control information between the controller and the second physical switch. | 02-13-2014 |
20140169379 | RELAY APPARATUS AND CONTROL METHOD THEREOF - A disclosed relay apparatus includes: a generator that generates, upon receipt of a first packet that includes a first identifier of a virtual machine that is newly executed in an information processing apparatus connected to the relay apparatus from the information processing apparatus, a second packet that includes a second identifier of the virtual machine, which is different from the first identifier, and requests to set relay for the virtual machine; and a processing unit that sets the relay for the virtual machine by using the second identifier of the virtual machine, which is included in the second packet generated by the generator or received from the information processing apparatus. | 06-19-2014 |
