The paper describes high-performance hardware controller development. The designed device allows to implement FDAL—A aircraft function and provides reduce of the development and certification costs.

Designed controller consists of the unique hardware-only platform and set of hardware-only applications. Each of application implements specific algorithms so the whole device performs the assigned objectives.

The platform architecture based on the reflective memory concept. That means the of virtual common memory for all application, and specific strictly determined memory exchange algorithms.

Each application represents by hardware module performs the task exclusively assigned to it. The platform has ability to control some equal applications.

Designed controller architecture has the modular-system roots, that aims to excellent scalability and flexibility characteristics and allows to implement new functions without the existing functions implementation modification.

The controller development is divided to two independent tasks — platform and application development. After that the IMA integration in performed. As a certification approach the task-by-task certification method (as described in DO-297) is suggested.
