Arm Instruction Emulator Tutorials

  • Human head showing understanding.

  • Get started with Arm Instruction Emulator

    A series of simple examples to demonstrate how to compile SVE code, run the resulting executable and analyze runtime behavior with Arm Instruction Emulator.

    Get started
  • A line drawing representing full value procurement.

  • Analyze SVE applications

    Use a basic instrumentation client to perform runtime analysis on your high-performance application. This enables you to gain insights into your application's execution behavior and identify heavily-used loops and instruction sequences.

Build an emulation-aware client

Learn how to modify the existing native-only clients to also handle emulated instructions, and to write emulation aware clients of your own.

Source code for the instrumentation clients is provided with the Arm Instruction Emulator build, in the samples directory:

/path/to/your/arm-instruction-emulator-<xx.y>_Generic-AArch64_<OS>_aarch64-linux/samples/

The files in this directory are inscount_emulated.cpp, opcodes_emulated.cpp and memtrace_simple.c. You can modify and enhance these for your specific analysis. See Building Custom Analysis Instrumentation for instructions on how to do this.
