# vendor_ohos

## Introduction

The repository is mainly developed by OpenHarmony community, rather than the
typical certain manufacturer, mainly including the development of QEMU products
with characteristics such as graphics, soft bus, etc.

## Software Architecture

Graphic display product samples of virt platform supporting QEMU's ARMv7-a
architecture, samples of virt platform supporting RISC-V architecture,
samples of esp32 board supporting Xtensa architecture, samples of virt
platform supporting C-SKY architecture, and samples of Cortex-M4 architecture.
