A processor is provided that implements a replay mechanism to recover from soft errors. The processor includes a protected execution unit, a check unit to detect errors in results generated by the protected execution unit, and a replay unit to track selected instructions issued to the protected execution unit. When the check unit detects an error, it triggers the replay unit to reissue the selected instructions to the protected execution unit. One embodiment of the replay unit provides an instru...

A method for stick and spoke replay in a processor. The method of one embodiment comprises dispatching an instruction for execution. The instruction is speculatively executed. It is determined whether the instruction executed correctly. The instruction is routed to a replay mechanism if the instruction did not execute correctly. It is determined incorrect execution of the instruction is due to a long latency operation. The instruction is routed for immediate re-execution if the incorrect executi...

A replay attack prevention technique uses a secret algorithm exchanged between client and servers computers. The algorithm is used to periodically alter a special replay key. The replay key may then be used to alter the message sent or alter the digest appended to the message such that the message and or its digest varies as time progresses. An unscrupulous third party who replays a stolen operation message would be unaware of the replay key and its variation. Any stolen message that is replayed...

A hearing aid includes a sound replay capability. The hearing aid can operate in a normal mode, augmenting sound as the sound occurs, or the hearing aid can operate in a replay mode (typically in response to input from the wearer of the hearing aid), replaying sound beginning up to a specified duration of time prior to the current time.

A microprocessor may include a scheduler configured to issue operations and a load store unit configured to execute memory operations issued by the scheduler. The load store unit is configured to store information identifying memory operations issued to the load store unit. In response to detection of incorrect data speculation for one of the issued memory operations, the load store unit is configured to replay at least one of the issued memory operations by providing an indication to the schedu...

A picture-in-picture window is opened in response to a user-entered replay command received while displaying a live state of video content on a screen. At least a portion of the video content is replayed on one of the screen and the picture-in-picture window while continuing displaying of the live state of the video content in the other of the screen and the picture-in-picture window.

Systems and methods for recording and replaying client-server transactions on selected clients in order to gauge the performance of the client-server system from the perspective of the client. In one embodiment, a method comprises playing back a set of recorded transactions on a client, monitoring selected performance-related parameters at the client, and transmitting monitored data to the server for analysis or for viewing by a system administrator. The set of transactions is recorded on a firs...

A method for providing instant replay is disclosed, including receiving a video and an audio stream from a source. Each media unit includes at least one video frame and at least one or more corresponding audio frames which further includes a first video frame that is independently decodable. Each media unit is an independently decodable entity. The media units have a fixed duration. The media units are stored in a memory. A number of starting addresses are stored in a table. The sequence header ...

The invention, in one embodiment, is a method for committing the results of at least two speculatively executed instructions to an architectural state in a superscalar processor. The method includes determining which of the speculatively executed instructions encountered a problem in execution, and replaying the instruction that encountered the problem in execution while retaining the results of executing the instruction that did not encounter the problem.

A replay equalization circuit for reproducing digital image information recorded on a recording medium includes a transducer for reading the digital image information, an equalization circuit connected to the transducer for equalizing an output of the transducer based on a speed information input, a clock recovery circuit connected to the equalization circuit for extracting a clock signal from an output of the equalization circuit for latching the output of the equalization circuit in response t...
