Overview

This repository contains outer-product-based matrix multiplication kernels for ARM Cortex-M4 microcontrollers such as Arduino Nano 33 BLE.

Installation

Before cloning and running the MEMA-MM sketch, please download and install the folowing dependencies:

• CAKE_on_CPU (https://github.com/vnatesh/CAKE_on_CPU/)
• Arduino IDE

Quick Start

The current Arduino sketch (MEMA-MM.ino) contains example programs running MM using different inner and outer product kernels.

Running Experiments:

Before running experiments, make sure the following additional dependencies are installed:

• Cortex-M4

  • Mbed OS 6.15.1
  • ARM CMSIS-DSP Library version 5.8.0

• Cortex-A72

  • ARMPL 21.0.0
  • ARM Compute Library (ARMCL) version 21.11
  • OpenMP 4.5
  • perf version 5.4.157

• Intel-i9 10900K

  • OpenMP 4.5

The experiments are organized in separate directories for each CPU architecture tested. Each arch-specific directory contains sub-directories corresponding to figures. To run an experiment and plot the associated figure, simply enter the directory and execute the run.sh file. An example to generate Figure 12 for the Cortex-A72 CPU tested is shown below. Experiments should be performed in sudo mode to enable permissions for hardware profiling.

~/MEMA-MM$ cd experiments/Cortex-A72/Fig-12
~/MEMA-MM/experiments/Cortex-A72/Fig-12$ ./run.sh
