Abstract: A computerized system and method for testing and analyzing problems with communications networks is disclosed. The system computerizes and automates the testing of such networks by providing a computer with interface software that can communicate with the variety of different test equipment that is currently available. The system automates process that was previously performed manually by an engineer or technician.

Abstract: A program having a plurality of concurrently executing versions is debugged. A version of the program to be debugged is selected from the plurality of versions of the program, and that selected version is debugged. As one example, the selection is responsive to the receipt of at least one task of the computing environment that is associated with the version to be debugged. The debugging of the selected version does not affect other versions of the program, other programs executing within the computing environment or other tasks using that version.

Abstract: To address the need for enhanced real-time analysis, Texas Instruments Inc. has developed a standard embedded infrastructure for its DSPs that provides unique visibility into real-time program execution. Integrated with TI's Code Composer Studio development environment, this infrastructure consists of two components: 1) DSP/BIOS, a tiny target-based run-time system that captures event and statistical information for the application and uploads it to the host (via a standard physical link such as JTAG) as the application executes in real-time; this DSP/BIOS system is integrated with the target application (C or DSP assembler); 2) Scope, a suite of host-based tools that allows designers to visually trace, monitor, and probe the DSP application as it executes in real time.

Abstract: A method of detecting illegal execution of code sequences includes the steps of: setting an active identifier to a first sequence identifier of a first code sequence, executing at least part of the first code sequence, calling, from the first code sequence, a second code sequence having a second sequence identifier, providing (20) a caller sequence identifier and a callee sequence identifier, checking (21) whether the callee sequence identifier is the same as the second sequence identifier, checking (23) whether the caller sequence identifier is the same as the active identifier, and generating (27) an alarm signal if either of the checks provide incorrect results.
