What benefits can Java Programming Language bring to your Embedded Systems?

  • Increase software productivity: This high-level programming language enables automated complex tasks such as memory allocation, which allow you focus on solving application problems and not on software design issues.
  • Reduced UI specification cycles: MicroEJ provides an instant simulation and PC prototyping platform to debug and test binary code. Embedded UI can be easily prototyped and validated with marketing and end-customers before hardware availability.
  • Same user experience for all devices: MicroEJ hardware abstraction capabilities allow to design one Embedded UI and deploy it on several products from low to high-end 3rd Party devices such as smartphones. Without re-designing your Embedded UI, you can offer your customers the same user experience on your entire products portfolio.
  • Flexible design process: Simulation allows short iterative tests with project stakeholders (marketing, ergonomics, R&D …) and brings versatile capabilities to your design process.
  • Leverage semiconductor innovations: Java virtualisation interface and universal software capabilities allow you to choose the latest electronic innovations without impacting software. You can easily run your application on low-end architecture and deploy it on another mid-range architecture without changing your software application. Of course such portable capabilities also help to manage MCU obsolescence without extra software development costs.
