Agenda• What is SAW?• Why use SAW?• Tracing, how does it work?• Demos

… “Creating trace files for SAW”… “Visualising custom trace events”… “Identifying performance issues”… “Detecting memory leaks”

• More features to come• Summary• Q&A


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


UTF Architecture

/ Eclipse


Demos• “Creating UTF files for SAW”• “Visualising custom trace events”• “Identifying performance issues”• “Detecting memory leaks”


More features to comeCPU profiler• Filter function chart by threads• Split thread chart per CPU• Reporting


More features to comeMemory analysis• Call stack• CLI


More features to comeThread Analysis• Chart view

… Scheduling

• Filter by… Thread… CPU


SummarySAW• New class of visualisation and analysis tools• Helps Symbian OS software development• Trace-driven based on UTF• First release in December 2008
