FX3 CPU port to multiple consumers without the one to many API

Is there a way to set up the FX3 SDK so that the CPU port can be used as a source for data across multiple consumers without going throught the one to many API.  I'm trying to pull off dummy data across 3 endpoints in an asynchronous way.

I didn't quite understand the functionality you're trying to achieve. Please add a little more information.

Please let me know why you don't want to use the API? Multicast would be the synchronous approach, you should be able to use one to many for the asynchronous approach. I'm trying to understand how/why it does not fit your application.

Regards,

Anand

The emulation I'm writing has multiple threads accessing the USB target at the same time.  All I'm tring to do is dummy up some response on each endpoint (3 bulk, 2 isochronous) without having to interlace the CPU socket across each endpoint.  Performance is important in this setup.  The way I understand the one to many is that the CPU socket would be sequencially assigned to each interface.  I don't want to do that.  Is there a method of just allocating memory for each 'ifunction' and assigning the consumer to that area?
