UtilitiesDebug and profiling

PVRTrace• OpenGL ES (1.1, 2.0 and 3.0)API call tracing• Provided as…- Stand-alone GUI- Recorder libraries- Linux installer application- Android controller apk• Features- Records GL calls, data and therender state for any number offrames- Playback frames, calls, andranges of calls- Profiling and analysis functionality- Can record over the network if therecording libraries are set to do so18© 2012 Imagination Technologies Ltd.

What is PVRScope?(and why should I use it )• Provided as…- Static library• Features- Provides hardware and software counters forGPU monitoring in real-time- Minimal impact in performance1. Save the data for off-lineperformance comparison- Script the performance analysis!2. Graph the data in real time- Just copy/paste from our PVRScopeexample- Quickly identify performance spikeswhile in-game testing3. Send data to custom profilingtools4. Send custom data to PVRTune- Use custom counters, custom markersand editable data19© 2012 Imagination Technologies Ltd.

PVRTune• PowerVR performance analyser basedon PVRScope• Provided as…- Stand-alone GUI- Per-platform PVRPerfServer application• Features- Provides hardware and software counters forGPU monitoring in real-time- Minimal impact in performance- So small its on by default in most drivers- Uses a network connection to transferinformation between host & client applications- No special builds of application required to doperformance analysis- Can remotely edit data registered withPVRScope- Can display custom marks and counters toenable analysis of custom data20© 2012 Imagination Technologies Ltd.
