34 results about "Interactive debugging" patented technology

An interactive system for debugging programs in which a persistent data base system responds to update queries containing debugging information from a debugging information source and to read queries on the debugging information from an interactive interface. The interactive interface produces the read queries in response to inputs from users and formats the results of the read queries as required by the user. One source of inputs is a standard Web browser for which the interactive interface functions as a Web server. The system also includes a command channel by which the source of debugging information receives commands from the interactive interface. In one embodiment, the command channel is implemented in the data base. In a disclosed implementation, the source of debugging information provides memory debugging information. Also disclosed are techniques for using an automatic memory management system to reduce memory fragmentation and heap footprint size.

Systems and methods are disclosed for performing interactive debugging of shader programs using a non-preemptible graphics processing unit (GPU). An iterative process is employed to repeatedly re-launch a workload for processing by the shader program on the GPU. When the GPU encounters a hardware stop event, such as by reaching a breakpoint in any thread of the shader program, encountering a hardware exception, or failing a software assertion in the shader program, the state of any executing threads is saved, graphics memory is copied to system memory, and any currently executing threads are killed to enable the GPU to process graphics data for updating a display device. Each pass of the workload may result in incrementally more data being processed. In effect, the changing state and variable data resulting from each pass of the workload has the effect that the debugger is incrementally stepping through the shader program.

A method, a system, and an apparatus for identifying and correcting sources of problems in synthesized speech which is generated using a concatenative text-to-speech (CTTS) technique. The method can include the step of displaying a waveform corresponding to synthesized speech generated from concatenated phonetic units. The synthesized speech can be generated from text input received from a user. The method further can include the step of displaying parameters corresponding to at least one of the phonetic units. The method can include the step of displaying the original recordings containing selected phonetic units. An editing input can be received from the user and the parameters can be adjusted in accordance with the editing input.

Visual representations of multiple call stacks in a parallel programming system include a stack segments graph constructed by coalescing data from multiple stacks. The graph has nodes that represent stack segments and has arcs between adjacent segments. Similar stack frames are represented by the same node. In a stack prefix view of the graph, arcs are directed from a node representing stack frames to a node representing subsequently executed stack frames. In a method-centered view, an arc is shown between a node representing stack frames of a selected method and a node representing adjacent stack frames. The graph can be based on call stacks of all tasks or all threads, or based on call stacks of tasks or threads flagged by a user. Stack frame, thread, and / or task details are also displayed.

A computerized method of characterizing a DUV includes executing in a verification environment (VE) a set of verification tests to stimulate the DUV to collect test results from the DUV. The method further includes collecting a set of failure data for the test results; and generating sets of common failures based on clusters of features of interest in the set of failure data. The method further includes generating a set of hints from the common failures; wherein the hints indicate a potential failure mode or a potential root cause failure of the DUV for the test results for the simplified set of tests; and generating a set of debug data from the clusters of features of interest. The method further includes transferring the set of hints and the set of debug data to a user computer for storage, display, and use in an interactive debug session of the DUV.

A process and system for interactive debugging of a computer program, is provided. One implementation involves providing a class for an object oriented computer program capable of executing on a computer system, the class having class methods defining a semantic field of the class; automatically monitoring the class during execution of the program, and leveraging said class methods by executing the class methods upon object-typed variables to obtain a pseudo-field value; and presenting the pseudo-field value along with fields of the said object-typed variables, on a user interface for debugging purposes.

A development application leverages the programmability of shader execution units in the graphics processing subsystem to make graphics processing subsystem state data accessible to applications executed outside the graphics processing subsystem. The development application modifies shaders to include state output instructions adapted to direct a shader execution unit to copy graphics processing subsystem state data to a location in the computer system that is accessible to applications executed outside of the graphics processing subsystem. Following the execution of the state output instructions, the shader execution unit can be halted or can continue executing the shader. The development application can modify the shader to include state restoration instructions adapted to direct the shader execution unit to set state data of the graphics processing subsystem to previous or new values. The development application can dynamically modify shaders with state output and restoration instructions to update state data of the graphics processing subsystem.

The invention is a configurable general synchronized / asynchronized serial communication debugger and debugging method. The debugging method consists of two modes: one is interactive, another is. In the first mode, two serial ports works independently, to cooperate with the target module of the debugging respectively; in the second mode, the two serial ports together with the target debugging module forms a ring, to participate the communication among target modules. Serial port debugging program works on host processors, which can be divided into two parts: configuration managing program and debugging program.

A test system that enables real-time interactive debugging of a device under test (DUT) using native customer code. A translation module may format, in real time, debug commands, corresponding to a user input, into a format recognizable by instruments in a tester. The user input may be a test program or test instructions written in a high-level programming language. The translation module may translate the user's debug commands into lower-level test instrument commands, based on which the tester may apply control signals to a processor in the DUT to test subsystems of the DUT. A result of the test may be provided to the translation module, which may, in real time, format another debug command, or provide an indication of the result to the user. The translation module may thus enable a user to step-through and modify native customer code in an interactive manner to debug a DUT.

Methods and measurements systems are disclosed relating to dynamic measurement prioritization by multiple software interfaces. A first software interface with a low priority may be conducting a first measurement on a device under test (DUT) through a driver connected to a measurement device. A second software interface with a higher priority may initiate a request to conduct a second measurement on the DUT. In response, the driver may automatically determine that the second software interface has a higher priority than the first software interface and may halt the first measurement and conduct the second measurement. The driver may notify the first software interface that its access to the measurement hardware has been revoked, and the first software interface may enter a monitoring mode to monitor the results of the second measurement.
