RISC-V Matrix Project

This is a demo project for matrix extension proposal.

Modules are shown below.

• riscv-matrix-spec: The matrix extension proposal
• llvm-project: llvm toolchain to support matrix extension proposal
• riscv-isa-sim: Spike ISS to support matrix extension proposal
• chipyard: Chipyard project to support matrix extension proposal with BOOM Core
• riscv-pvp-matrix: RISC-V Matrix Extension ISA Verification using RISC-V PVP
• riscv-dnn: A small DNN library for RISC-V, using RISC-V Vector and Matrix extensions

Quick start

prepare and clone repos.

$ export RISCV=~/opt/riscv
$ export PATH=$RISCV/bin:$PATH

$ git clone https://github.com/riscv-stc/riscv-matrix-project
$ cd riscv-matrix-project
$ git submodule update --init

compile and install llvm toolchain

$ cd llvm-project
$ mkdir -p build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=$RISCV \
    -DCMAKE_BUILD_TYPE=Release -DLLVM_OPTIMIZED_TABLEGEN=On \
    -DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld" \
    -DLLVM_LINK_LLVM_DYLIB=On ../llvm
$ make -j`nproc` && make install
$ cd ../..

compile and install gnu toolchain

$ cd riscv-gnu-toolchain
$ git submodule update --init --recursive
$ mkdir -p build && cd build && ../configure --prefix=$RISCV
$ make -j`nproc`
$ cd ../..

compile and install spike ISS.

$ cd riscv-isa-sim
$ mkdir -p build && cd build && ../configure --prefix=$RISCV
$ make -j && make install
$ cd ../..

run riscv-dnn on spike for dnn operator and resnet-50 tests.

$ cd riscv-dnn
$ pip3 install -r requirement.txt

$ cd test/ops/
$ make -j8
$ cd ../..

$ cd test/models/resnet50/
$ python3 gen_weight_bin.py
$ python3 gen_input_bin-fp16.py
$ python3 gen_header.py
$ python3 test_resnet50.py

TODO

• update modules to support latest version of proposal.
• add chipyard simulation & verification & prototype documents.
