TimingProfiler for x86 helps you identify application parts that cause unsatisfactory execution times. It delivers results as soon as there is compiled code, and thus can be used very early in the development process, when measurements on physical hardware are costly or impossible.
This makes TimingProfiler ideally suited for constantly monitoring timing behavior during software development and in model-based development environments.
The goal is not to give precise worst-case guarantees like with aiT, but to enable development of applications in a timing-conscious way without cumbersome measurements on physical hardware. The analysis is applicable when no hardware is available yet, or the application is not mature enough for measurements.
Key benefits
- TimingProfiler gives detailed information about the execution time and time-critical paths.
- The analysis is purely static. No access to physical hardware and no code instrumentation are required.
- The analyzer does not need to be stimulated with concrete inputs. By default, it takes all potential inputs into account.
- Nevertheless, the analysis can be restricted to specific execution scenarios if desired.
- The tool shows call and control flow graphs, and displays all relevant information about the executable.
- Hotspots and bottlenecks can be identified at early development stages so that late-stage integration problems can be avoided.
- This provides for easy integration into the development process, and enables application in continuous test and integration frameworks.
- TimingProfiler can be seamlessly coupled with StackAnalyzer to additionally take the stack behavior into account, providing a unified approach to addressing resource usage.
Architecture variants and extensions
The supported instructions sets are:
- x86-32 (ia32, Intel 32)
- x86-64 (Amd64, Intel 64)
- x87
- MMX
- 3DNow!
- SSE
- SSE2
- SSE3
- SSE4.1
- SSE4.2
- AES
- AVX
- AVX2
This covers a wide array of architectures, including 8086, 80286, i386, i486, and AMD K6-2E+. However, for the purposes of licensing and pricing, TimingProfiler for 16-, 32-, and 64-bit x86s are treated as three separate products. Likewise, i386DX and IntelDX4/Am486 are supported separately.
