Marto: Modern ARithmetic Tools for high-level synthesis

Marto provides C++ headers to implement custom sized arithmetic objects such as:

  • Custom sized posits and their environment (including the quire)
  • Custom sized IEEE-754 numbers
  • Custom sized Kulisch accumulators (and sums of products)

Marto usage

Marto is a header only library. It is based on Hint in order to provide support for many HLS backends.

Building unit tests

  • Make sure to have the Hint library installed
  • Make sure to have the Softposit library installed
  • Make sure to have the ap_int library installed
  • Clone the current repository
  • Create a build directory
  • Create a cmake build
  • Make the tests
  • Launch the tests
git clone https://gitlab.inria.fr/lforget/marto 
cd marto
mkdir build
cd build 
cmake .. -DSOFTPOSIT_H=<PATH_TO_SOFTPOSIT_INSTALL_DIR>/source/include
         -DSOFTPOSIT_LIB=<PATH_TO_SOFTPOSIT_INSTALL_DIR>/build/Linux-x86_64-GCC/softposit.a
         -DAP_INT_INCLUDE_DIR=<PATH_TO_AP_INT_INCLUDE_DIR>
         -DBUILD_UNIT_TEST=1
make
ctest
