An analog-to-digital converter (ADC) ( ) for sampling high speed video signals includes Pre-amplifiers ( ) electrically coupled to Post-amplifiers ( ) that are electrically coupled to output latches ( and ). A sampling clock signal ( ) clocks the output latches ( and ) to sample an input analog electronic signal to provide a digital representation thereof. The ADC ( ) includes an auto-zeroing function to cancel bias voltages at the Post-amplifiers ( ) during a video signal horizontal blanking time period. The ADC ( ) includes a bit dithering function by alternating sets of reference voltages into the Pre-amplifiers ( ) increasing bit resolution. The ADC ( ) includes wired interconnect interpolation between the Pre-amplifiers ( ) and Post-amplifiers ( ) and between the Post-amplifiers ( ) and the output latches ( and ).

An electronic circuit includes a selectively configurable differential signal interface and a selection control input for selecting one of a plurality of standard differential signal interfaces for configuration of the differential signal interface. The selection control input selects one of the following plurality of standard differential signal interfaces: reduced swing differential signaling (RSDS), low voltage differential signaling (LVDS), mini low voltage differential signaling (mini-LVDS), and bussed low voltage differential signaling (BLVDS), for configuration of the differential signal interface. The electronic circuit may also include a plurality of selectable voltage sources ( ) and a plurality of selectable current sources ( ), for selecting, in response to an input signal at the selection control input, at least one of an operating D. C. voltage, a standard differential signal voltage, and a standard differential signal current for the differential signal interface.

A cache-based system management architecture named “the Collective” automates system management and supports mobile computing. The Collective manages systems by manipulating virtual appliances, each encapsulating a system state. A virtual appliance (VA) may comprise a virtual network of VAs. Distributed repositories separately storing the VAs and user data. Publishers create and maintain VAs. A user plugs a bootable portable storage device implementing a VA transceiver (VAT) into a host computer. The VAT, comprising a Manager, a Cache Client, and a virtual machine monitor (VMM), authenticates the user, retrieves a copy of the latest version of a subscribed VA from the appropriate network repository, obtains user data, and automatically backs up the user data over the network in the background while running the subscribed VA. Multiple VAs can be run at the same time. With the novel caching protocol and cache charging process, the Collective performs well and has numerous advantages.

Various approaches for virtual appliance management are described. In one approach a virtual appliance repository stores one or more virtual appliances and is coupled to the host computer via a network. A storage device stores a transceiver program capable when executed on said host computer of requesting and receiving the virtual appliances, and generating for each received virtual appliance a respective local copy on the host computer of each received virtual appliance. The local copy is private to the host computer. The transceiver program further binds the virtual appliances to the host computer and obtains user data relevant to the virtual appliances. The transceiver program runs each of the virtual appliances from the respective private local copies on the host computer.

Replay-time-only functionalities in a computer program are executed only during replay in a virtual machine and are skipped outside of replay. If a replay-time-only functionality is detected during the replay of a program execution in a virtual machine, the replay may be paused and the virtual machine state may be saved. The replay-time-only core functionality is executed. When this execution is complete, a prior state of the virtual machine may be restored and the replay may be resumed.
