External Memory Bus (Linux)

The External Memory Bus, referred to as "External Interface Module" in Freescale documentation, is a bus protocol for communication from an integrated circuit to an external memory device. The external memory bus is typically used to connect high speed devices like FPGAs, DSPs, secondary Ethernet controllers, CAN controllers, etc.
