LMU-3x40 Training Guide
Revision & Date
1.6 – 03/24/2021
The design and architecture of this software platform achieve the intended benefits by following
these principles:
1. Modularity and compactness of system. One module envelops one concept and/or
task.
2. Commonality across modules to allow more efficient methods to understand code
across different platforms and developers.
3. Adaptability to allow for easier changes within the product or platform, with the goal
that one module is applicable to other modules.
4. Portability that allows for streamlined ports of application code base on different
operating systems and hardware chipsets using both OS and Hardware abstraction
layers.
