VIP Alpha Blending Mixer Problem

Thanks for that suggestion. I implemented it on Monday and have been working with it ever since trying to debug what is going on.

Part of the problem has been with a module I designed that feeds data into the mixer. It decodes part of the data stream to create the data and alpha streams for one of the layers, and it wasn't flexible enough to accommodate the way the mixer acts during it's initial startup. I think I have that part worked out now.

The other part of the problem is that I am using the Avalon-ST Splitter IP module to split my alpha and data streams to two different mixers. The data stream appears to be OK, but on the alpha stream, the Splitter allows only the header word of the data packet through, and then drops its ready line even though the devices downstream from it have their ready lines high. My guess is that the mixer is looking at the data streams and is expecting a control packet, even though the documentation says it just passes on whatever it receives. I am working on my own way to split the alpha stream so I don't have to use the splitter there.
