Embedded Software Solution for Smart Things

MicroEJ Virtual Execution Environment (VEE) is a standard, safe and secure embedded software platform capable of running on any processors including microcontrollers (MCU), microprocessors (MPU) and System on Chip (SoC).

MicroEJ VEE

The Virtual Execution Environment for Embedded Things, with all standard services

• Virtualization of hardware and middleware
• Secure Multi-app trusted execution model (sandboxes)
• Standard services such as IP networking, cryptography, file systems, serial
• Multi- programming languages technology mastered by 10+ million developers
• True digital twin simulators
• Support for all sensors/activators and communication means

MICROEJ VEE is available as a simulated environment called Virtual Devices, and as an embedded runtime for processors from major silicon vendors.

VEE Virtual Device

Digital twin of your future product.

It allows to design embedded software applications on comfortable PC/desktop, using a true simulator while the actual electronics is being designed.
The Virtual Device simulates the code execution, along with all peripherals such as displays, connectivity, sensors and any specific hardware feature of your system.

VEE Embedded Runtime

VEE Runtime is tailored for your hardware.

MICROEJ VEE features the smallest virtual processor MEJ32, a 32-bit virtual core, along with tons of libraries.
VEE = MEJ32 + libraries
Applications developed on the Virtual Device execute the same without any change on the real device: write once, run and deploy anywhere.
MEJ32 comes in various flavors, named the architectures, virtualizing all available ISA of the embedded markets: ARM Cortex-M, ARM Cortex-Ax, RX, V85, MIPS32, TriCore, Tensillica, etc. : MicroEJ MEJ32 architectures

Release your product faster to the market

• Apps can be downloaded dynamically to increase product functionality or to  provide security updates
• Requests can be pulled from end-user or pushed by a fleet manager

Support the creation of your ecosystem or marketplace

• Offer a standard development environment shared by 10+ million developers
• Open API’s without disclosing your middleware and intellectual property
• Allow any number of developers to use MICROEJ Studio and Virtual Devices
• Manage apps with your store (public or private)

MicroEJ VEE

A secure environment for IoT systems

Applications can be loaded onto a device in a trusted way but what can ensure the application is actually safe?
MICROEJ VEE is also called MicroEJ Trusted Execution Environment:

• provides access control to the system resources
• prevents system crashes
• protects confidential data from unwanted access
