What is SAW?• Visualisation and Analysis tools for Symbian OS

… Trace debugging… Optimising performance… Analysing memory usage

• Eclipse-based… Eclipse 3.3… Carbide.c++ 1.3

• Used by … Developers… System architects

Why use SAW?• Symbian OS specific

… Process and threads… Exes, DLLs and functions… Memory models

• Based on Symbian’s Unified Trace Framework… Symbian OS and custom trace events

• Integrated analysis tools… CPU profiler, Memory analysis, Trace viewer, Thread Sync

• Extensible framework… Demand paging (Q1/2009)

Tracing, how does it work?Software tracing

… Add trace points into the source code… Runs on both hardware and emulator… Is intrusive

Unified Trace Framework (UTF)… Runtime and build-time controlled… Generates compact binary output on the target

Consumed by SAW… Allows custom tracing
