# Arm Virtual Hardware

- [Overview](./arm_virtual_hardware.md#overview)
  - [Getting started](./arm_virtual_hardware.md#getting-started)

## Overview

Arm® Virtual Hardware is an accurate representation of a physical System on Chip and runs as a simple application in a Linux environment for easy
scalability in the cloud and removes dependency from silicon availability. Powered by Amazon Web Services (AWS), developers can launch Amazon Machine Image
(AMI) running as a virtual server in the cloud. The Arm Virtual Hardware is configured with the Corstone™-300 MPS3 based Fixed Virtual Platform (FVP),
compiler and other tools.

### Getting started

To take advantage of Arm Virtual Hardware, you would need to have an AWS account and follow the steps below:

 1. Login to your AWS account.
 2. Go to the AWS Marketplace and search for [Arm Virtual Hardware](https://aws.amazon.com/marketplace/pp/prodview-urbpq7yo5va7g).
 3. Subscribe to the Arm Virtual Hardware Amazon Machine Image.
 4. Launch the AWS instance.


 To access the Arm Virtual Hardware AWS instance via ssh, accept the prompt  to generate a *.pem* key while creating the instance or add it later.
 You can then access the AWS instance over ssh: `$ ssh -i <mykey.pem> ubuntu@<ec2-ip-address>`. 
 It may be necessary to change the permissions for mykey.pem with `$ chmod 400 mykey.pem`.


### Useful Links
Note that you can register to receive free AWS credits to use Arm Virtual Hardware from [here](https://www.arm.com/company/contact-us/virtual-hardware).

You can find more information about Arm Virtual Hardware [here](https://arm-software.github.io/VHT/main/overview/html/index.html).

Once you have access to the AWS instance, we recommend starting from the [quick start guide](../quick_start.md#Quick-start-example-ML-application) in order to get familiar
with the ml-embedded-evaluation-kit. Note that on the AWS instance, the FVP is available under `/opt/FVP_Corstone_SSE-300`.

In order to view the FVP window when launching on the AWS instance a VNC is required.
