Ubuntu 22.04 Build Instructions for MATHLIB

Python3 Setup

• We auto generate test cases via python scripts packaged in the library
• Please ensure that you have the following python3 packages installed
  • numpy, scipy, and scikit-learn

Environment Setup

• Run the executables on EVM using CCS (Code composer studio)
• Setup needed for the compiler for CGT7x
  • Download CGT7x Compiler Installer and install
  • export CGT7X_ROOT=${CGT7X_COMPILER_DIR}
• Path setup
  • export PATH=${CGT7X_ROOT}/bin:${PATH}

Build

• MATHLIB utilizes CMake to build, ensure that system has CMake v3.16.0 or higher
• Build options:
  • SOC=AM62A/j721e/j721s2/j784s4/j722s/AM275
  • DEVICE=C7504/C7100/C7120/C7524/C7524
  • TARGET_PLATFORM=PC/""
  • KERNEL_NAME
  • BUILD_TEST=1 OR BUILD_EXAMPLE=1 OR AUTO_TEST=1
  • MATHLIB_DEBUGPRINT=1/0
  • MATHLIB_TESTPRINT
  • ALL_TEST_CASES=1 OR TEST_CASE=TestCaseID
  • CMAKE_EXPORT_COMPILE_COMMANDS=TRUE
  • CMAKE_BUILD_TYPE=Release/Debug
  • AUTO_TEST=1/0 (builds all test cases and libraries)
• Example CMake commands
  • To build MATHLIB_sqrt for target on j722s and run performance test cases:

    •  cmake -B build -DTARGET_PLATFORM="" -DBUILD_TEST="1" -DKERNEL_NAME="MATHLIB_sqrt" -DSOC="j722s" \
      -DDEVICE="C7524" -DMATHLIB_DEBUGPRINT="0" -DALL_TEST_CASES="1" -DCMAKE_EXPORT_COMPILE_COMMANDS="TRUE" \
      -DCMAKE_BUILD_TYPE="Release" 

  • To build MATHLIB_div for host emulation on j722s and run example code

    •  cmake -B build -DTARGET_PLATFORM="PC" -DBUILD_EXAMPLE="1" -DKERNEL_NAME="MATHLIB_div" \
      -DSOC="j722s" -DDEVICE="C7524" -DMATHLIB_DEBUGPRINT="0" -DCMAKE_EXPORT_COMPILE_COMMANDS="TRUE" \
      -DCMAKE_BUILD_TYPE="Release" 

  • To build MATHLIB_exp for host emulation on j722s and run test case 2 with debug print statements

    •  cmake -B build -DTARGET_PLATFORM="PC" -DBUILD_TEST="1" -DKERNEL_NAME="MATHLIB_exp" -DSOC="j722s" \
      -DDEVICE="C7524" -DMATHLIB_DEBUGPRINT="1" -DTEST_CASE="2" -DCMAKE_EXPORT_COMPILE_COMMANDS="TRUE" \
      -DCMAKE_BUILD_TYPE="Release" 

  • To build all tests cases and libraries for release for j722s for target

    •  cmake -B build -DTARGET_PLATFORM="" -DAUTO_TEST="1" -DSOC="j722s" -DDEVICE="C7524" \
      -DALL_TEST_CASES="1" -DCMAKE_BUILD_TYPE="Release" -DMATHLIB_DEBUGPRINT="0" 

  • Then run:

    • cmake --build build -j<num_cores> 

• MATHLIB can also be built using the Visual Studio Code's build configuration feature
  • Rename vscode/ to .vscode/
  • In the settings.json, change build parameters as needed
  • "Build" and "Run" buttons can be used to build for target/PC and run for PC
• Note: If changing build configuration options significantly (e.g. changing between target and host emulation builds), delete build folder before rebuilding
• Note: AUTO_TEST binaries don't run on AM275 due lack of external memory; please build binaries with TEST_CASE flag
  

Run

• To run MATHLIB kernels on a PC:

  • bin/Release/test_MATHLIB_<kernel_name>_<device>_x86_64 

    OR

    bin/Debug/test_MATHLIB_<kernel_name>_<device>_x86_64 

    • Ex:

      bin/Release/test_MATHLIB_tan_C7524_x86_64 

• To run MATHLIB kernels for target
  • To reproduce numbers given in the datasheet, run the .out program on the EVM in No Boot Mode
