The compressed component data file may be decompressed to produce a copy of the component data file, and the component data may be extracted from the component data file. Multiple component data files may be received at different times, compressed to produce corresponding compressed component data files, and the compressed component data files may be stored in a designated location.

Abstract: Techniques for developing and exchanging virtual machine implementations and/or support library implementations are described. In one embodiment, the virtual machine design specifies a set of functions for executing all or substantially all support library operations that are dependent on the implementation of the virtual machine. When a developer desires to substitute one virtual machine implementation for another, the developer is able to basically “plug-in” the second virtual machine implementation with minimal impact on the support libraries since both virtual machine implementations provide implementations for the set of specified functions that are dependent on the implementation of the respective virtual machine. Conversely, different support libraries may be utilized in conjunction with a particular virtual machine implementation.

The sample mode may include single sample per pixel mode and multiple samples per pixel mode. The graphics system may be further operable to generate a single sample per pixel for certain windows of the screen in order to provide backwards compatibility with legacy systems.

Abstract: A method for reducing sub-threshold leakage during the burn-in procedure for a semi-conductor is disclosed.

Abstract: A system and method are provided for managing information concerning a network flow comprising packets sent from a source entity to a destination entity served by a network interface. A network flow is established for each datagram sent from the source entity to the destination entity. A flow key, identifying the source and destination entities, is stored in a data structure along with information concerning validity of the flow, sequence of data in the flow datagram and how recently the flow was active. Once a flow is established, it is updated each time a packet containing data from the flow's datagram is received. When such a packet is received, an operation code is generated for identifying whether the packet is suitable for a particular network interface function. An operation code may, for example, indicate that a packet contains data to be re-assembled with other data from the same flow. Another operation code may indicate that a packet is not suitable for data re-assembly.
