Abstract: Provided is a method for scheduling operations called by a task on a real-time or non-real-time processor. Execution durations are provided for operations. A call is received from a task for an operation. A determination is made of a latency requirement for a first processor and of the execution duration of the called operation. The called operation is executed on the first processor in response to determining that the determined execution duration is less than the latency requirement. The called operation is executed on a second processor in response to determining that the determined execution duration is greater than the latency requirement.

Abstract: A data transfer control device includes an ATA device-side I/F which transfers data between the data transfer control device and an ATA host through a bus ATABUS1, an ATA host-side I/F which transfers data between the data transfer control device and an ATA device through a bus ATABUS2, a first interface which transfers data through a first bus, and a transfer controller which controls data transfer among the device-side I/F, the host-side I/F, and the first interface.

Abstract: A multiple protocol address register method between a communication terminal and the register server includes transmitting a first register request for requesting to register a first protocol address from the communication terminal to the register server; storing the first protocol address and the identification to the register server; transmitting a response to the first register request from the register server to the communication terminal together with a first communication rule; transmitting the second register request from the communication terminal to the register server on the basis of the first communication rule; storing, when the second register request is created based on the first communication rule, the second protocol address in the register server; and transmitting a response to the second register request from the register server to the communication terminal.

Abstract: A data transfer interface system is provided that directly transfers data from one data storage drive to another data storage drive under the control of a host. The host and data storage drives are jointly connected to one another with data lines and control lines. Each data storage drive is connected separately to the host with a read/write command line. The host initializes the data storage drives providing initialization data to the drives where the data may include position information and commend information. After initialization, the host concurrently instructs one data storage drive to read the data from the drive while the other data storage drive writes the data to memory.

Abstract: The disclosed technology can be used to develop systems and perform methods that receive and process I/O requests directed to at least a part of a logical unit of storage. The I/O requests can be associated with different times corresponding to when such I/O requests were received. Nodes that include non-overlapping address ranges associated with the logical unit of storage can be formed in response to receiving the I/O requests and such nodes can be subsequently organized into a tree data structure. The tree data structure can serve as a basis for determining address overlap, for example to enable processing a first operation associated with a first one of the I/O requests in accordance with the first I/O request's receipt time, while one or more other operations associated with a different I/O request may be processed irrespective of that different I/O request's receipt time.

Abstract: Transferring data elements from a source to a destination includes providing a transmission queue at the source, where data elements in the transmission queue are transferred from the source to the destination, determining an optimal length for the transmission queue, where the optimal queue length is inversely proportional data latency time at the destination, and, if the optimal length is greater than an instantaneous length of the transmission queue, adding data elements to the transmission queue. Adding data elements may include adding a number of elements corresponding to a difference between the optimal length and the instantaneous length of the transmission queue. Determining optimal length may include dividing a constant by the data latency time at the destination. Transferring data elements may also include providing a network between the source and the destination.

Abstract: A system includes an information processing apparatus and a peripheral which are connected to each other. Initially, the information processing apparatus transmits, to the peripheral, a request to use a service provided by the peripheral. The peripheral determines whether to grant use permission to the received request, and notifies the information processing apparatus which has transmitted the request of the determination result. The peripheral stores information associated with the information processing apparatus to which use permission is granted in response to the request. The information processing apparatus then receives, from the peripheral, a response to the request.

Abstract: A network controller with a bootable Host Bus Adapter, particularly suitable for iSCSI applications is described. In one example, this includes, a host bus interface, a register to the host bus indicating a mass storage device, a network interface, and a boot memory extension including a driver for the mass storage device that binds to a BIOS.

Abstract: A cellular phone. The cellular phone comprises a connector, a first memory module, a second memory module, and a controller. The connector is used for physically connecting the cellular phone to an external device. The first memory module stores phone data. The second memory module stores application data received from the external device. The controller determines whether the connector is connected to the external device. If the connector is not connected to the external device, access right of both the first and second memory modules is granted exclusively to the cellular phone. If the connector is connected to the external device, access right of the first memory is granted exclusively to the cellular phone, and access right of the second memory module is granted exclusively to the external device.

Abstract: A method comprises providing a free buffer pool in a memory including a non-negative number of free buffers that are not allocated to a queue for buffering data. A request is received to add one of the free buffers to the queue. One of the free buffers is allocated to the queue in response to the request, if the queue has fewer than a first predetermined number of buffers associated with a session type of the queue. One of the free buffers is allocated to the queue, if a number of buffers in the queue is at least as large as the first predetermined number and less than a second predetermined number associated with the session type, and the number of free buffers is greater than zero.

Abstract: Communicating via a network using a universal network driver interface is disclosed. It is determined whether a universal network device interface (UNDI) driver is installed. A UNDI driver is scanned for if it is determined that no UNDI driver is installed. In the event a UNDI driver is found, a PCI network device that is associated with the UNDI driver is scanned for. If a PCI network device associated with the UNDI driver is found, the UNDI driver is loaded and initialized for the PCI network device.

Abstract: A data processing system includes at least a first processing node having an input/output (I/O) controller and a second processing including a memory controller for a memory. The memory controller receives, in order, pipelined first and second DMA write operations from the I/O controller, where the first and second DMA write operations target first and second addresses, respectively. In response to the second DMA write operation, the memory controller establishes a state of a domain indicator associated with the second address to indicate an operation scope including the first processing node. In response to the memory controller receiving a data access request specifying the second address and having a scope excluding the first processing node, the memory controller forces the data access request to be reissued with a scope including the first processing node based upon the state of the domain indicator associated with the second address.
