Trace Analysis Tool and Library (TATL)

Product Description

The Trace Analysis Tool and Library (TATL™) helps software developers tune and debug real-time multiprocessor and multicore processor applications. Designed for system sizes from a few to several hundred processors, the TATL tool provides insight into the dynamic interactions among processors in systems of all sizes.

Debugging real-time applications can be complex, whether they are based on multiprocessors or multicore processors such as the Cell Broadband Engine™ (BE) processor. Source code debuggers and printf statements affect the real-time execution of the application while providing little understanding of the communications and dependencies among processors. The TATL tool uses minimally intrusive trace analysis to clarify processor interactions. User-defined events are logged in local memory with minimal overhead, allowing the system to proceed with real-time processing. By logging these events at the beginning and end of interactions such as message sends/receives and requests/grants of a shared resource, a developer can collect data on the complex communication and control patterns of the application.
