Have you recently been sceptical of usinga contact-based access system in your office or a public place? This trait is a major concern in most places for a valid reason. An access surface in a public place is used by many individuals, which makes it a potential source for contracting the deadly Covid 19 virus. Taking this into account, iWave Systems, a leading embedded solutions provider, has successfully demonstrated an alternative solution using facial recognition technology. The solution helps customers with a zero-contact access application by using individuals' faces to authorize access to a commercial/industrial space, home/office, transportation, banking, and Government sites.

Facial Recognition:

 

Facial Recognition is the process of recognizing the identity of a person by using their facial features against a previously stored database.

It is a technology that uniquely identifies or verifies a person by comparing and analysing patterns based on the person’s facial details. The face capture process transforms the analogy information into a set of digital information, while the face match process verifies the information with a database of known faces to find a match.

iWave Solution :

 

The facial recognition demo is running on iWave’s development board based on the NXP® i.MX8M Mini applications processor. The power-efficient edge computing platform with a SODIMM form factor is coupled with a MIPI Camera module (1080p@30 fps) , MIPI Display (1920 x1080 60fps), and multiple connectivity options. Through the support of key features such as camera, display, connectivity, and the NXP eIQ machine learning software, the i.MX 8M Mini board provides an intelligent platform for the development of facial recognition systems.

 

 

Demo Environment

 

 

 

The captured image and stored images are fed to the application to recognize the faces. eIQ OpenCV ML software compares the novel face features with the known face images in the Django framework database. Real-time data logging can be configured to send the information with the alert for authorized or unauthorized detection.

 

NXP eIQ OpenCV Machine Learning Software:

 

iWave i.MX8M Mini board is integrated with the NXP eIQ OpenCV machine learning softwarewhich enables faster time to market while reducing the development complexity. The eIQ software includes pre-optimized libraries and tools to perform machine learning and computer vision applications. The eIQ software enables developers to accelerate the development flow of the ML applications by taking full advantage of the underlying i.MX8M Mini SoC. The software supports C++/Python/Java API’s which provides the programming flexibility to the developers.

iWave Systems, a leading embedded solutions provider company based in Bangalore has successfully demonstrated Xen virtualization hypervisor on their i.MX8 QM SoC based System on Module. The  multi-core SOM comprises of 2x Arm® Cortex® -A72 @1.8 GHz and 4x Arm® Cortex®-A53 @1.2 GHz and 2x additional Cortex®-M4F @ 266 MHz, rendering a highly powerful  integrated solution on a SMARC R2.0 compatible module.

i.MX8 QuadMax SMARC SOM                                                                          i.MX8 QM SMARC SOM

To fully explore the enormous computing capability of the i.MX8 QM SOM, iWave has implemented virtualization of hardware using the open source type 1 Xen hypervisor. The Xen hypervisor enables multiple virtual machines to be created over a single hardware resource, each virtual machine capable of running its own independent operating system. This enables the i.MX8 QM SOM run multiple operating systems concurrently on the same physical board. The Xen hypervisor allows maximum utilization of resources thereby improving overall system performance and efficiency.

About Xen hypervisor

Xen is an open source type-1 hypervisor developed by the University of Cambridge and is now being developed by the Linux Foundation. Xen runs directly on the hardware to manage guest operating systems. Hence, it's also considered as a bare metal hypervisor. Xen has less overhead enabling faster performance and Operating Systems are more secure as they don't rely on base OS for installing the hypervisor.

A system running the Xen hypervisor contains three components:

  • Xen Hypervisor
  • Domain 0 (Dom0) – Privileged virtual machine running on the hypervisor that can access the hardware directly and interact with other unprivileged virtual machine running on the system.
  • Multiple DomainU (DomU) – Unprivileged virtual machine running on the hypervisor and have no direct access to hardware (e.g. CPU,memory, timer and interrupts cannot be directly accessed)
 

During the initial system start-up, Xen hypervisor launches the Dom0 that runs the Linux operating system. The Dom0 has unique privileges to access the Xen hypervisor compared to other Domains. Dom0 manages the DomU, the unprivileged domains running on the system. Dom0 allocate and map hardware resources for the DomU domains.

Advantages: -

  • Less overhead compared to type-2 hypervisors since type-1 hypervisors make use of ARM virtualization extensions.
  • Having faulty/buggy OS in DOM-U domain will not disrupt the functionalities of DOM-0 OS.
  • DOM-U driver domains can support legacy hardware drivers no longer supported by new OS.
  • Have completely isolated workspaces with different requirements. Eg: gaming and multimedia.
  • Better resource management since resources rarely used will not be powered on if the domain it belongs to is not booted.
 

Xen demo on iWave’s i.MX8QM SOM

In iWave’s Xen Demo on i.MX8QM Board, the DOM-0 OS runs Linux 4.14.98 from eMMC and DOM-U runs Android Pie 9.0 from USB drives. Such a system can be used where there is a need for both faster, highly reliable OS (such as Linux) and more multi featured slightly slower OS (such as Android) to be running on the same hardware.
