An apparatus for a processor includes a first scoreboard, a second scoreboard, and a control circuit coupled to the first scoreboard and the second scoreboard. The control circuit is configured to update the first scoreboard to indicate that a write is pending for a first destination register of a first instruction in response to issuing the first instruction into a first pipeline. The control circuit is configured to update the second scoreboard to indicate that the write is pending for the fir...

Either one of the fields of an interlaced television signal is designated as top field as indicated by a first selector signal. The presence of a second selector signal indicates bottom field. A regenerated vertical synchronization signal is furnished for the first horizontal synchronization signal following vertical synchronization in top field. This regenerated vertical synchronization signal resets a counter which counts horizontal synchronization signals repetitively to a count of five. A se...

A microprocessor computer system includes random access and read only memories and a set of operator switches permitting the storage of game play information. During operation of the amusement device, game play is monitored and the score required to receive a free play is periodically adjusted to maintain a selected free play percentage. The percentage is determined by either the factory setting or the operator through the operator switches. The data used to compute the free play percentage is c...

A technique is provided for breaking a stalled condition or livelock in a processor having a replay queue. A livelock or stalled condition is detected. One or more instructions are temporarily stored in a replay queue. A release or break in the livelock or stalled condition is detected, and the instructions are then unloaded from the replay queue for replay or re-execution. For a multi-threaded processor, a stall is detected in one of the threads. Instructions of the stalled thread are temporari...

Instructions asserted in a microprocessors instruction pipeline (3) are accompanied by control information, comprising a group of bits, asserted within a control information pipeline (5) that is synchronized to the instruction pipeline. At the execution stage, the control information is interpreted and appropriate action taken. The control information may indicate that the instruction has been reasserted (asserted again following an initial assertion) and may also indicate the number of times th...

The present invention is directed toward a method for storing, verifying and salvaging user-defined queries in a database environment. The method comprises retrieving a stored query and an associated stored application version identifier and comparing the stored application version identifier with a current application version identifier. If the application version identifiers do not match, the entire stored query is checked for validity. If an error is found in the stored query, the query is pa...

The virtual reality imaging system takes a multidimensional space that contains real world objects and phenomena, be they static or dynamic in nature, and enables a user to define a point in and/or a path through this multidimensional space. The apparatus then displays the view to the user that would be seen from the point in and/or path through the multidimensional space. This view is filtered through user definable characteristics that refine the real world phenomena and objects to a perspecti...

System for collecting data, relating to the showing of specific video information registered together with a core signal onto a registration carrier. The carrier is forwarded by the information supplier to one of a number of display stations comprising each at least a video display apparatus for displaying the registered video information and comprising a processor for detecting said code signal and deriving therefrom data about the starting time and the period during which said video informatio...

A data recording and/or reproducing device for recording and/or reproducing data on or from a recording medium includes information concerning the recording method used for recording data on a recording medium, that is the encoding/decoding instruction data is recorded on the recording medium along with the data. Using the encoding/decoding instruction on the recording medium, specifically the decoding instruction, the data on the recording medium is restored by a DSP. The data recording and/or ...

A user can selectively replay portions of a computer program execution, so that the entire program need not be run again to support further test and debug. A run-time instrumented version of the program is created by inserting special instructions into the original program. The run-time instrumented version is executed to create trace files of memory accesses and system calls, as well as identification of interrupts. During execution of the run-time instrumented version, a state of each accessed...
