Solution


This section describes the structure and design of the encoding and decoding support in the SDL Suite. It is intended to give you an understanding of the solution.

Functionality

The main goal is to help you to develop executable files, applications or simulators, that can:

ASN.1 coder framework contains the following functional modules:

All these modules will be described in more details in this chapter.

Functionality Access Interfaces

When using the coder functionality, you can choose between different access interfaces. They all share the same implementation.

The SDL and C interfaces are not identical. They are adapted to the properties of the languages.

It is preferred to access the coders from SDL when the encoded bit-pattern must be further processed in the SDL system. One interesting example is when the bit pattern is sent in a signal to another process.

It is preferred to access the coders in C-code in the environment files when the SDL-system does not process the bit pattern internally, for example when sending it to a protocol in the environment.
