Abstract: Computer program testing after source code for the computer program has been modified is performed more quickly, by using execution conditions. First, second, and third execution conditions are determined. These execution conditions are used to perform testing of the program to determine whether the program is properly functioning. Particularly, test data on which basis testing of the computer program is performed can be classified as first test data, second test data, third test data, or fourth test data. The program prior to modification of the source code is tested by employing the first, second, and third test data. After the source code is modified, the program is retested by employing only the third and the fourth test data. The program is thus properly retested after source code modification by employing only the third and the fourth test data, without having to employ the first and the second test data.

Abstract: Disclosed are embodiments that provide near real-time monitoring of a control application in a manufacturing environment to detect and determine the root cause of faults within the control application. The embodiments monitor the flow of data within the control application during events (i.e., transactions, stages, process steps, etc.). By comparing a dataflow path for a near real-time event with historical dataflow path records, dataflow interruptions (i.e., fails) within the control application can be detected. By determining the location of such a dataflow interruption, the root cause of the control application fail can be determined. Additionally, the invention can generate summary reports indicating the status of the control application. For example, the summary reports can quantify the performance and/or the effectiveness of the control application. These summary reports can further be generated with drill downs to provide a user with direct access to the records upon which the reports were based.

For each node identified in the set of differences, the first and second call trees are then analyzed to identify at least one parent node that is the root cause of the difference in the execution data.

Abstract: A cryptographically secure, computer hardware-implemented modular reduction method systematically underestimates and randomizes an approximate quotient used for computation of a remainder. The randomizing error injected into the approximate quotient is limited to a few bits, e.g. less than half a word.

In addition to a computational unit and operations sequencer, the computing hardware also includes a random or pseudo-random number generator for producing the random error. The modular reduction method thus resists hardware cryptoanalysis attacks, such as timing and power analysis attacks.

Abstract: A method for transmitting digital messages used during testing of microprocessors. Each message includes at least one data packet. To transmit a message, each data packet is divided into successive segments of predetermined size, each segment being classified in accordance with one or the other among five types depending on whether it contains a start of message (SM), intermediate data (NT), an end of packet (EP), and end of message (EM); or it is an empty segment (ID). As each segment is sent, an identification signal characterizing the succession of the segment concerned and of the preceding segment is sent. To reduce the number of transmitted segments, a segment containing both the start and the end of a message is classified as being a segment containing an end of message, and a segment containing both the start of a message and the end of a first packet of the message being classified as a segment containing an end of packet.

The master card drops all the data packets if the CRC check packet associated with the data packet is not correct.

Abstract: A dynamic analysis tool uses anomaly detection to find heap-based bugs. In spite of the evolving nature of the heap, programs generally exhibit several of properties of their heap usage that remain stable. Periodically, during the execution of the program, the analysis tool computes a suite of metrics which are sensitive to the state of the heap. These metrics track heap behavior, and the stability of the heap reflects quantitatively in the values of these metrics. The ranges of stable metrics, obtained by running a program on a multiple input training set, are then treated as indicators of correct behavior, and are used in conjunction with an anomaly detector to find heap-based bugs.

Abstract: A server application discovers its relevant data objects and generates a report of the current states of such objects at a moment in time that is relevant to a detected failure. Responsive to a request for a server application state, the application can identify root objects; discover data types, values, and related objects through recursive traversal and analysis of the object hierarchies; and generate a state description of the application for review and analysis by others.

The state description can be analyzed by validation tools to detect where the error might exist in the application and how the error might be corrected.

Abstract: A program circuit activates a pass signal when a first program unit is programmed. The first program unit is programmed when a test of an internal circuit is passed. A mode setting circuit switches an operation mode to a normal operation mode or a test mode by external control. A state machine allows a partial circuit of the internal circuit to perform an unusual operation different from a normal operation when the pass signal is inactivated during the normal operation mode. By recognizing the unusual operation during the normal operation mode, it can be easily recognized that a semiconductor integrated circuit is bad. Since a failure can be recognized without shifting to the test mode, for example, a user who purchases the semiconductor integrated circuit can also easily recognize the failure.
