More like a single chip anything, like a DVD, VCR, MP3 player etc. The large number of IOs is required to interface to graphical displays in direct drive mode (or with some drivers on the glass). The DMA capabilities suggest that it is intended to interface to the main device datapath directly or not. Quote a consumer application with lots of IO and some realtime pretentions, like an inkjet printer, DVD or MP3 player, CDROM CD-RW, better VCR (double ?) etc and you have its place. At 16mm^2 I suspect that it requires BGA technology for assembly. Unless the toaster people have mastered that maybe wait a little bit.
