# 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.

## 介绍

该仓库托管OpenHarmony社区开发的，而非某个厂商单独开发的典型产品样例代码，主要
包括类似QEMU(Quick Emulator)的图形、软总线等特性产品的开发。

## 软件架构

支持QEMU的ARMv7-a架构的virt平台的图形显示产品样例，支持RISC-V架构的virt平台的
样例，支持Xtensa架构的esp32开发板的样例，支持C-SKY架构的virt平台的样例，以及
Cortex-M4架构的样例。
