文档简介

Transformer enable AUTOSAR systems to use a data transformation mechanism to linearize and transform data.

Transformers can be concatenated to transformer chains which are executed by the RTE for intra-ECU and inter-ECU communcation that is configured to be transformed.

A transformer provides well defined function signatures per each communication relation (port based and signal based), which is marked for transformation. The function signature depends on the transmitted data elements (Client/Server operation signature or Sender/Receiver interface signature) only. The output of a transformer will be always a linear byte array.

A more powerful system can chain multiple transformers where the input of the first transformer in the chain gets the data from the RTE. Each following transformer uses the output of the preceding transformer as input. All transformers following the first one then have generic signature with just a byte array as IN and OUT parameter. Such an architecture could be used to design systems, where you can flexibly add functionality like safety or security protection to a serialized stream.
