OCC: The Open CIM Compiler

This repository contains MLIR-based compilation infrastructure and a suite of tests for a Computing-In-Memory device simulator.

See the 'sim_build' branch for additional simulation benchmarks, cross-compilation build config and evaluation results.

End-to-end CIM compilation tests

The provided tests are based on the following steps:

  1. MLIR code is generated from the functions defined in a Tensor Comprehensions (TC) file
  2. MLIR is lowered through CIM dialect (and others) and compiled to an object file
  3. A test application is compiled together with the MLIR object file and linked against CIM runtime library
  4. The test application calls the compiled TC functions through their MLIR C interfaces

Initializing submodules

git submodule init && git submodule update

Building tests

Ensure that paths to the following executables are set correctly at the project root level CMakeLists.txt:

  • MLIR_OPT_BIN
  • MLIR_TRANSLATE_BIN
  • LLC_BIN
  • TECKYL_BIN

Tests can then be built by (optionally) creating a build directory, invoking cmake and running make as follows:

  • mkdir build
  • cd build
  • cmake ..
  • make

The built tests application can be found in build/bin directory.
Other build artifacts, e.g. generated MLIR files, can be found in build/tests/TEST_NAME subdirectories.
