Anti-malware emulation systems and methods
In some embodiments, antivirus/malware behavior-based scanning (emulation) is accelerated by identifying known code sequences and executing pre-stored native-code routines (e.g. decompression, decryption, checksum routines) implementing the functionality of the known code sequences before returning to the emulation. During emulation, target machine code instructions are compared to a set of known signatures. If a known code sequence is identified, the emulator calls a native code routine and caches the current instruction address. If the emulator subsequently reaches a cached address, a native code routine may be called without scanning the data at the address for known signatures. Signature scanning may be performed selectively for instructions following code flow changes (e.g. after jump, call or interrupt instructions). The emulator may also call native-code routines implementing virtual operating system calls, and native-code unpacked file reconstruction routines that reconstruct unpacked files from the contents of virtual memory for scanning by a content-based malware scanner. |

Hierarchical categorization of media assets and user interface for media player
An improved hierarchical user interface for a handheld media player is disclosed, which classifies media assets that an on-line merchandiser intends to sell to the user as hidden files. The files are invisible to a user without a user's intended and persistent interaction with a user input device of the player. The media assets that an on-line merchandiser intends to sell to the user are stored in the unused storage capacity of the player and are organized in a single structure as those media assets owned by the user. A method includes a means that a user actuates a user input device until the hidden files are displayed. Furthermore, a method is disclosed to utilize a file storage system of a portable media player more effectively and efficiently. The unused storage capacity is then used by the on-line merchandiser to store media assets, which have not been purchased by the user at the moment when they are received by the media player. The capacity occupied by the media assets from the merchandiser is adjusted dynamically based upon the required capacity by the user at a specific time. The media assets stored are managed based on their assigned priorities. |

Machine translation using language order templates
Many machine translation scenarios involve the generation of a language translation rule set based on parallel training corpuses (e.g., sentences in a first language and word-for-word translations into a second language.) However, the translation of a source corpus in a source language to a target corpus in a target language involves at least two aspects: selecting elements of the target language to match the elements of the source corpus, and ordering the target elements according to the semantic organization of the source corpus and the grammatic rules of the target language. The breadth of generalization of the translation rules derived from the training may be improved, while retaining contextual information, by formulating language order templates that specify orderings of small sets of target elements according to target element types. These language order templates may be represented with varying degrees of association with the alignment rules derived from the training in order to improve the scope of target elements to which the ordering rules and alignment rules may be applied. |

System and method for filtering communications at a network interface controller
A system and method and method for filtering communications at a network interface controller is provided. The network interface controller is coupled to a baseboard management controller through a sideband communications channel. The network interface controller filters packets to the baseboard management controller on the basis of the address within the packet that identifies the device that caused the packet to be generated. The network interface controller transmits to the baseboard management controller only those packets that were generated in response to a command issued by the baseboard management controller. |

Cognitive radio communication terminal and method for detecting collision using feature detection
A cognitive radio communication terminal including a transmission processing unit to divide data by a quiet time slot that is allocated at a first point in time of a collision detection period, to transmit at least one portion of the divided data to a reception side, and a sensing unit to determine whether at least one of a feature information and an energy of another terminal is detected in a channel with the reception side during the quiet time slot of the first point in time. Where neither the feature information nor the energy of the other terminal is detected based on a determination of the sensing unit, the transmission processing unit transmits the remaining divided data. |

Wireless communication terminal and wireless communication method
A communication terminal used in a mobile communication system complying with a carrier sense multiple access scheme is disclosed. The communication terminal includes: a receiving unit configured to receive a wireless packet transmitted by another communication terminal or a base station; a determination unit configured to determine periodic transmission timing of the communication terminal based on determination criterion information included in the wireless packet; and a transmission unit configured to periodically transmit wireless packets to the base station based on the transmission timing. |

Multi-protocol communication circuit
A multi-protocol communication circuit, for example, a serializer-deserializer (SerDes) circuit for communicating between an internal logic circuit and an external link includes a select terminal configured to accept a select signal representing a plurality of mode select signal. A SerDes core is coupled to the select terminal and configured to transmit outbound data conforming with a first communication protocol in response to a first mode select signal and conforming with a second communication protocol in response to a second mode select signal. The SerDes core is also configured to receive inbound data respective to a first communication protocol in response to a first mode select signal and respective to a second communication protocol in response to a second mode select signal. Advantages of the invention include the ability to provide high bandwidth communications between integrated circuits that employ different SerDes protocols. |
