UNCLASSIFIED Hi Jim, Just revisiting this. Has there been any progress on getting the hdl version of the bias worker working? I'm looking for a simple "out-of-the-box" xml example to test the comms between the fpga and the cpu. Cheers, Josh
________________________________ From: James Kulp [mailto:[email protected]] Subject: Re: [opencpi_dev] FPGA<->RCC example [SEC=UNCLASSIFIED] Hi Josh, The basic idea is to simply "connect the workers". There are two ways to do this: 1. Via the control API (create workers, get their ports, and connect them). An example is the canny example, although it has a bunch of OpenCV stuff that is not relevant. (See the control API document). 2. Via the (recently finally added) XML technique of creating an XML description of the application and its connections. An example is bias_xml (biasFile.cxx). Where you could assign the bias worker (selection set to "model == hdl"). (Unfortunately this technique is only shown in the various "*_xml" examples, and not documented yet. Probably a this point the xml technique is simplest. Both the XML and Control API are agnostic to the type of worker. The testRpl program is used to do this too, although it is a somewhat contorted example. There is some glitch that currently prevents the "bias_xml" from working with the "bias" worker assigned to an FPGA. We'll be looking at that shortly.
