Abstract: A method, system and computer program product for controlling access to data files stored in a repository is disclosed. The method includes receiving a request for a data file from a requester. The request specifies a data format preference for receiving the data file.

Abstract: Power consumption may be reduced through the use of power gating in which power is removed from circuit blocks or portions of circuit blocks in order to reduce leakage current. One embodiment uses a modified state retention flip-flop capable of retaining state when power is removed or partially removed from the circuit. Another embodiment uses a modified state retention buffer capable of retaining state when power is removed or partially removed from the circuit. The state retention flip-flop and buffer may be used to allow for state retention while still reducing leakage current. Also disclosed are various methods of reducing power and retaining state using, for example, the state retention flip-flops and buffers. For example, software, hardware, or a combination of software and hardware methods may be used to enter a deep sleep or idle mode while retaining state.

Abstract: A system is described for managing interaction between an untimed HAL portion and a timed HDL portion of the testbench, wherein the timed portion is embodied on an emulator and the un-timed portion executes on a workstation. Repeatability of verification results may be achieved even though the HAL portion and the HDL portion run in parallel with each other. A communication interface is also described for synchronizing and passing data between multiple HDL threads on the emulator domain and simultaneously-running multiple HAL threads on the workstation domain. In addition, a remote procedural-call-based communication link, transparent to the user, is generated between the workstation and the emulator. A technique provides for repeatability for blocking and non-blocking procedure calls. FSMs and synchronization logic are automatically inferred to implement remote procedural calls. A subset of behavioral language is identified that combines the power of conventional modeling paradigms with RTL performance.

Abstract: A wireless communication system and method for managing content of a remote device (104) is described. A transceiver (202) receives usage information from the remote device (104) and communicates event content to the remote device at a reporting time.

The processor (204) determines the reporting time based on the usage activity of the remote device (104) during the predetermined time period. For another embodiment, the processor (204) determines a time period of inactivity based on the usage activity of the remote device (104) during the predetermined time period, and minimizes communication of the event content to the remote device during one or more future time periods corresponding to the time period of inactivity.

Abstract: Encryption hardware built on a network interface card is provided by the present invention for encrypting data sent from a computer to a network. A block of data is retrieved from the network interface card, encrypted using encryption hardware, and inserted into a data packet. A flag is set in the packet header to indicate the encryption type. If the data packet is received by a system equipped with similar network interface card, decryption algorithm indicated by the flag is applied to the data using decryption hardware on the network interface card. The decrypted data is sent to re-assembly logic to rebuild the original message for the transmitted packets. The original message is sent to a computer memory via a system bus for further processing. If the data packet is received by a system not equipped with the network interface card, suitable software is provided to decrypt the data packet.

Abstract: An computer program product and a method is presented for diagnosing hardware and software problems on a network computer through the use of a diagnostic adapter card. The diagnostic adapter card is installed in an open slot in the system bus and thus has access to all the network computer electronics and peripherals. Diagnostic programs are run and the results are logged. By analyzing these results, the source of the problem can be determined and reported for service or repair. The diagnostic adapter card contains its own processor, read only memory, random access memory, and interface logic for connecting to the system bus, a set of external wrap cables for peripheral connector testing, and an external reporting device. Some tests require use of a wrap cable to connect two or more ports together. Other tests, such as system bus timing or memory integrity, do not require the use of wrap cables.

Abstract: A system and method is presented for synthesizing both a design under test (DUT) and its test environment (i.e., the testbench for the DUT), into an equivalent structural model suitable for execution on a reconfigurable hardware platform. This may be achieved without any change in the existing verification methodology. Behavioral HDL may be translated into a form that can be executed on a reconfigurable hardware platform. A set of compilation transforms are provided that convert behavioral constructs into RTL constructs that can be directly mapped onto an emulator. Such transforms are provided by introducing the concepts of a behavioral clock and a time advance finite state machine (FSM) that determines simulation time and sequences concurrent computing blocks in the DUT and the testbench.

Abstract: A communication system comprising a mobile station and a network implements a persistent packet data control channel that provides for a continuous exchange of control information, such as system information (SI) messages and handoff-related information. The mobile station implements the persistent packet data control channel by mapping the persistent packet data control channel to a packet associated control channel when a packet associated control channel is available and to a virtual associated control channel when a packet associated control channel is not available. The virtual associated control channel allows the mobile station to pass control information to network in the absence of an uplink Temporary Block Flow (TBF).
