Porting different functions with different number of parameters to DM6446.

Dear Sir:

I am trying to port my computer vision library to DM6446.

My idea is creating a module named IMYCV.

However, I suffered a difficult problem.

I knew that we must design our library APIs based on XDM so I use the example "scale" as a start point.

I want to ask that if I have a lots of functions in my library and most of them don't have the same number of parameters and data types passed in, how can I port this library?

It cofused me because the API I can only have is "control" and "process", and parameters passed into each of the functions should share the structure "InArg" and "OutArg". Of course I should design fixed inArg and OurArg structures in the begining so the fields in both structures are hard to think about.

I am not sure if I describe my problem clearly. If not, please let me know.

Thank you very much.

The best solution we currently have for implementing arbitrary algorithm functionality with Codec Engine is the IUNIVERSAL API, see the wiki article on Getting Started with IUNIVERSAL for details on how to get started. You should be able to leverage this to get your algorithm onto the DM6446, even easier if your algorithm is already compliant with XDAIS.

Dear Sir:

Thanks for your replying.

However, the article Getting Started with IUNIVERSAL says that "if you’re going the Montavista route, you’ll need to use MV 5.0 since it's a prerequisite to CE 2.20 and later",

Linux I am using now is not MV5.0, and that means I can't use IUNIVERSAL module.

If I can use IIMGDEC skeleton and stub instead, can you give me more help that how can I intergrate a lots of functions and only use the same fields in InArgs and outArgs?

Thank you very much.

This is a very good question, we have put together a wiki article that addresses extending not only inArgs and outArgs, but other data structures associated with other functions as well.

Please note that this wiki article also mentions some of the things to look out for when extending these data structures. I hope this helps.
