Softcore CICERO

Software simulator for the CICERO domain specific architecture.

This is a fork from Valentina Sona original git repository

Build

To build the library and the example application, install CMake, Make and a C++ compiler

mkdir build
cd build
cmake ..
make

# Optionally run tests
make test

Run example

./build/cicero ./test/programs/1

Use the library

Instantiate a CICERO object specifying:

1. Character window (min 1, multichar only): number of active characters in the sliding window.
2. Verbose setting (true/false): print execution information or match silently.

#include "CiceroMulti.h"

auto CICERO = Cicero::CiceroMulti(1, true);

The simulator takes in input the program files compiled by CICERO's compiler.

Set the program (can be set multiple times in the object lifetime) and run the desired matches:

CICERO.setProgram("program/to/run");

bool result = CICERO.match("RKMS");
bool result2 = CICERO.match("RACS");
