Performance of API's: VISA vs. DMAI

Andreas Nagel

Hello,

DMAI is built on top of the VISA API. A document or wiki page states, that DMAI can be used to quickly build demo applications. Is the DMAI API also suitable for developing software for use in a companies product? Or are there some disadvantages (e.g. performance), so that the VISA API should be used instead?

Brief recommendations are highly appreciated.

    Andreas:

        DMAI adds value by abstracting the driver interfacing and buffer handling. 

        Since you would have to perform the buffer handling anyways even without DMAI, using DMAI for the buffer handling would be an advantage since the code has been proven by writing the DVSDK demos.

        The DMAI is an open source project at: https://gforge.ti.com/gf/project/dmai/  , but from recent forum posts activity seems to be dying off.

        So, I would at least consider referencing or re-using the buffer handling modules of DMAI, especially if the application is doing lots of VISA calls to various codecs.
