API Changes for fast-forwording to latest IREE release with reduced code-size fix

API changes for accommodating lastest IREE release.

Remaining issues:
- Needed stack size is significantly increased
- ITCM size for mobilenet_v1_float increased from 1M to 1.5M
- ITCM size for some models is still >1M after this reduced code size fix and they are still disabled for now.

Springbok Model Execution Repository

This project contains ML model codegen and execution libraries/examples. The artifacts built from this project is targeted for RISC-V 32-bit baremetal machine (Springbok).

Prerequisite

If you get this project from Project Shodan manifest, you are all set. If not, you need to have following projects as well to build the project successfully.

This project needs to be at <dir>/sw/vec_iree

Code structure

  • build_tools: Utility scripts for the project
  • cmake: CMake Macros for the project
  • native_log: BSP support for the Linux userspace emulation
  • samples: Codegen and execution of ML models based on IREE
    • device: Device HAL driver library
    • float_model: float model examples
    • quant_model: quantized model examples
    • simple_vec_mul: Point-wise vector multiplication examples
    • util: Runtime utility library for model execution

Build the project

If you are running from Project Shodan repo, you can build the artifacts with m iree. If you download this project alone, you need to download/build IREE's host compiler, then at the top level directory

  cmake -B <output dir> -G Ninja \
     -DCMAKE_TOOLCHAIN_FILE="$(realpath sw/vec_iree/cmake/riscv_iree.cmake)" \
     -DCMAKE_BUILD_TYPE=MinSizeRel \
     -DIREE_HOST_BINARY_ROOT="$(IREE_COMPILER_DIR)/install" \
     -DRISCV_TOOLCHAIN_ROOT=$(TOOLCHAINRV32_PATH) \
     <dir>/sw/vec_iree
  cmake --build <output dir> --target all

Run the executables

You can run QEMU or RENODE emulation with the built executables. In Shodan repo, qemu_sim_springbok for QEMU emulation, and sim_springbok for Renode simulation. Out-of-repo emulation is possible but require more steps.

Test the executables

In Shodan, this project utilizes LLVM lit and FileCheck to test the ML executable performance. The tests are defined in the *_test.txt files under samples. To run the test, at the Shodan top level directory

lit --path <Filecheck dir> -a sw/vec_iree/samples

Filecheck in Debian testing is under /usr/lib/llvm-11/bin

Add -D FEATURES=internal to enable the internal model tests. Add -D RUNNER=qemu to enable the qemu tests.
