Software Profiling

Profiling reports offer process-to-source-code drill-down analysis of

the hotspots on your CPU.The three available views can be based

on either processor time or PMU counters such as instructions,

cycles, cache misses.

• Call Paths - powerful hierarchical software profile view that can

be used to see statistics per process, thread, library and functional

call chain

• Functions - flat function level list of hotspots

• Code - the ultimate resource to pin-point hotspots within

functions at both source code and disassembly levels.

Applications and the kernel can write text messages or graphics frames into the

Streamline driver for visualization.

Annotations

Reconcile debug and performance analysis with a simple and

powerful solution; code annotations. From simply tracking machine

state changes on a timeline or cross-relating the screen content

with performance issues, this simple code instrumentation links

your software to the Streamline Performance Analyzer.

The Call Paths view displays CPU time or PMU event count (e.g., cache misses), per

process, thread, and function call tree.

Energy Analysis

The ARM Energy Probe is an easily deployable USB accessory that

can sample voltage, current and power from up to three probe

points in the system. It then synchronizes the data with system

performance metrics and the software execution trace.

Key Benefits:

• Low Total Cost of Ownership - no additional debug hardware

is required.All you need is the Streamline Performance Analyzer

and the Energy Probe.

• Everything in one place - make informed decisions based on

an integrated view of the ARM application processor and Mali

GPU performance counters, software profiling, code annotations

and power consumption data.

Power, current and voltage data can be displayed alongside thread activity and other

performance metrics to enable energy optimization
