An Open-Source Heterogeneous CGRA Architecture Design Space Exploration Framework

THRAM Framework

Template-based Reconfigurable Architecture Modeling Framework, including:

1. CGRA-MG: CGRA modeling and generation based on Chisel. Design a flexible CGRA template, and generate architecture IR and Verilog.

2. CGRA-Compiler: CGRA mapper, mapping DFGs to CGRA in batches. The mapping flow includes placement and routing, data synchronization, optimization, visualization, and configuration generation.

3. Bechmarks: DFGs in Json format derived from dot files.

4. CGRA-DSE: CGRA design space exploration based on Bayesian Optimization

Getting Started

Dependencies

JDK 8 or newer (for CGRA-MG)

SBT (for CGRA-MG)

CMake (for CGRA-Compiler)

C++-11 (for CGRA-Compiler)

HEBO (for CGRA-DSE)

CGRA-MG

Build and run

Using the script run.sh

cd cgra-mg
./run.sh

Or using sbt command:

cd cgra-mg
sbt "runMain mg.CGRAMG -td ./verilogDir"

CGRA-Compiler

Build

Using the script build.sh

cd cgra-compiler
./build.sh

Run

Using the script run.sh

./run.sh

Change the benchmark file path as you need. The generated result files are in the same directory as the benchmark.

CGRA-DSE

Using the script build.sh

cd analyzeDFG
./build.sh

Using the script dse.py

python3 main.py

Automatic DSE flow including benchmark analyzing, modeling and compiling , change the benchmarks as you need. Or implement the process step by step.
