Not much, You were right about the name, I saw I was wrong after sending it. It should teach me to reread before posting. But I wasn't talking about smartfusion for graphics but more for an example of how reconfigurable computing could look and that a few device do exist with the capacity. There also all the Virtex 2 and 4 with the powerPC embeded in the FPGA that can work as reconfigurable computing. Still the smartfusion is more affordable. The interest on on-chip flash is that everything is configured when powering up the system. With external flash it can take some time before the chip being programmed. That's part of the reason why we have the lattice xp2 doing the pci bridge on OGD1. The spartan take a few second to be properly programmed and it would be too long for a computer bios.
