STM32 FSMC/FMC and DS90CR285
A display link like that is inherently both very parallel and very high rate. A serial to parallel converter doesn't change the bandwidth requirements, and most display won't let you just send data in as slowly as you want.

What would you do with whatever you transmit/receive inside an Cortex-M4, anyway? It's not like a single picture is likely to even fit into RAM.
