General Information

STV3550

9/144

●

Readable and maintainable

The CTV100-LCD application software consists of 4 main layers based on these non-functional

requirements:

●

System Layer provides certain general-purpose components such as Handle or Link List

Managers. This layer also contains the Operating System Abstraction Layer (OSAL)

components which enable other layers to be OS-independent.

●

Driver Layer provides a hardware abstraction to the upper layers making them hardware-

independent.

●

Service Layer contains the components that provide the Application layer with high level

interfaces in order to manage the TV set. The set of Service components included in the

demonstration application are very useful for developing applications.
