Opt-VP

an extension to the RISC-V based Virtual Prototype (VP)

RISC-V based Virtual Prototype (VP)

Most hardware in the area of IoT and embedded systems only ever runs a single application.
To reduce the cost and increase performance the hardware can be tailored to this application.
Unfortunately, identifying, designing, and evaluating application-specific optimizations is complex and requires significant effort.

In order to combine the advantages of high-level and lowlevel approaches we propose this Virtual Prototype to automatically identify promising hardware optimization candidates based on recurring patterns.

For information about the base RISC-V VP please visit the base repository

:dart: Additional Features

  • Tracing of any RISC-V binary compiled for RV32IMAC
  • Generation of bounded execution trees for every instruction
  • Support for arbitrary scoring function for the analysis
  • Ouput dot visualization of iternal trees
  • export best sequences as json
  • full csv export for trees
  • reload scoring functions during runtime

:rocket: Getting Started

:wrench:Building the VP ###

Check out all submodules console $ git submodule update --init --recursive Afterwards console $ make will build the VP

For dependencies and detailed instruction on how to build the Opt-Vp please follow the instructions from the base RISC-V VP

To uninstall/clean use console $ make clean

:computer: Usage

The command line interface of the Opt-VP can be used according to the following scheme:

console $ ./vp/build/bin/tiny32-vp --intercept-syscalls <executable> --output-file <output-directory>

You can find examples on how to run and analyze programs in the ./runanddot.sh script: ./vp/build/bin/tiny32-vp --intercept-syscalls $input_file --output-file ./out/ --dot

Additional arguments include * --csv to export all trees as csv files * --dot to output dot files for the internal trees * --seq to output the best sequences used in opt-seq * -i to enter interactive mode after the simulation has finished
