An expert protocol analyzer, which records a protocol exchange between two or more hardware devices on a network or software modules in a multiprogramming environment. To validate a potential fix, the protocol is replayed in a simulated network environment, where a replay unit replaces the endpoint that is not available in the lab, or which in the lab operates with a different timing. The replay unit behaves like one of the two original units of the. Individual messages are adjusted for the loca...

A tool for emulation systems that obtains the state values for only discrete partitions of a circuit design. When a partition is being emulated, the emulation system obtains the input values for the specified partition at each clock cycle and the state values for the specified partition at intervals. Using the state and input values with a software model of the specified circuit design partition, the tool calculates the state values for the partition at every clock cycle. The software model may ...

According to one aspect of the invention, a microprocessor is provided that includes an execution core, a first replay mechanism and a second replay mechanism. The execution core performs data speculation in executing a first instruction. The first replay mechanism is used to replay the first instruction via a first replay path if an error of a first type is detected which indicates that the data speculation is erroneous. The second replay mechanism is used to replay the first instruction via a ...

A portable computer to facilitate the game of golf is programmed to record a golfer's score and keep track of various shots and the results of related wagering. Based upon such data and data regarding the layout of the golf course, the computer can provide real time recommendations for club selection as well as providing a summary of the results of a round of golf. Also, the computer can receive global positioning system (GPS) signals to locate a golf ball within a golf course.

A radar data recording and playback system comprising a recording adapter circuit for processing output signals from a radar apparatus for recording such on separate channels of a video tape recording apparatus, and a playback adapter circuit for processing the recorded radar data signals into proper form for operation of a radar visual display device. The adapters may also include means for processing heading signals and auxiliary inputs, such as audio signals, for recording such on a separate ...

A system is described for selecting and replaying desired tape segments of a recorded tape, a video tape for example, in any predetermined sequence. The system accepts an operator's designation of which segments of the tape are desired for replay and in which sequence those segments are to be replayed, irrespective of the location of the selected segments on the tape. An electronic controller, responsive to the operator's designations, causes the playback machine to replay each selected tape seg...

An instant replay system for a bowling scoring system is disclosed in which a video clip of a bowler's approach and deliver of a bowling ball and a video clip of the bowling ball subsequently entering a pin-fall area are filmed, compressed, and stored in a memory device, such as a hard drive. The instant replay system includes a controller for receiving user requests from a user input terminal of the bowling scoring system and for responding to such user requests by selecting a stored video clip...

A real time, instant replay time-motion analysis system of work measurement that utilizes computer assisted video techniques to simultaneously record and display an operator at work and the elapsed time for the performance of each elemental step in his work task. An observer provides an input signal each time a step is completed and a subsequent step initiated, thereby causing the display of elapsed time relating to the first step to freeze and a display indicating running time for the second st...

Methods and apparatus for performing a function (such as recording or playback) relative to an elongate information carrier located in a casing include the provision of a capstan at a distance from the casing and an extraction of a length of the information carrier out of the casing in a direction away from the casing by finger means. A portion of the extracted information carrier is placed onto the capstan with the finger means and the capstan is employed to advance the information carrier. The...

A processor is provided that includes an execution unit for executing instructions and a replay system for replaying instructions which have not executed properly. The replay system is coupled to the execution unit and includes a checker for determining whether each instruction has executed properly and a replay queue coupled to the checker for temporarily storing one or more instructions for replay. The replay queue may be used to store a long latency instruction, such as a load in which data m...
