Symbian lets developers see how code performs

Users can trace data and memory usage

Symbian has announced it is allowing developers to see how their code performs on the mobile operating system.

The Symbian Analysis Workbench (SAW) is a prepackaged set of free Eclipse-based tools for optimising Symbian C++ code, according to the company, which is in the process of being acquired by Nokia.

SAW has also been designed for future Symbian releases, said David Wood, Symbian's executive vice president for research.

For example, SAW will show the allocation of resources across different processors for Symmetric Multiprocessing (SMP) versions of the Symbian OS, Wood said.

SAW lets develops see trace data, or how instructions are executing on the processor, and monitor memory usage. It also has a CPU profiler, which shows which part of the application is using the most processor cycles, and a thread state reporter, which shows how threads relate to one another, Symbian said.

A 'target management' feature lets a developer control a device from a desktop PC. Files can be managed on the device using FTP, and commands can be executed using a TelNet agent.

The tool is rolling out worldwide and will be available as part of the Symbian Developer Network, an online forum for Symbian OS development, Wood said.
