4. The Alta Software Model
19 Sept 2007

5. The Layer 0 API Modules Written in ANSI “C” for portability.
Provides basic functions to map/read/write memory and to handle interrupts.
Each supported operating system will have it’s own Layer 0 module.
All OS dependencies will be in Layer 0.

6. The Layer 1 API Module Written in ANSI “C” for portability.
Provides all the functions needed to control Alta hardware.
The Layer 1 module is common for ALL operating systems. This layer is portable to any platform (if the platform supports ANSI “C”).

7. The Layer 2 API Modules
Layer 2 API modules encapsulate the Layer 1 functions for higher-level (object oriented) programming.
There can be many different Layer 2 modules for different languages or environments.
Alta provides a Layer 2 module for Microsoft .NET 2.0.

8. Microsoft .NET 2.0 Support
Alta provides a Microsoft .NET 2.0 assembly that makes the Layer 1 API functions available to .NET applications.
This can be used with any .NET language.
C#, C++, VB, etc.
Can be instantiated as a .NET “Remote Object” to control Alta hardware on remote systems over a network.
