is the Ironman board limited to 4 DMA and 4 Imagebuffer instances? VA 3.2.0 won't let me add a 5th one in my project and pass Design Rules Level 1. The resource index won't go over 3 for either one
The number fo DMA-Transfers is limited to 4. You can use InsertImage/AppendImage, InsertLine/AppendLine to show two images below of each other or next to each other using the Insert*/Appen* approach; please take care that these approaches require some synchronization memory for serializing lines or images. For two results/images that exist at the same time, please use InsertLine/AppendLine and a ImageFiFo (size 1 line per input) to handle the waiting time for the lines being forwarded one after the other. An image serialization is normally "cheaper" concerning hardware ressources that an additional DMA channel.
The amount of ImageBuffers (real frame grabber hardware RAM modules) is limited to 4.
