Emulate an (EP)ROM with mbed

Hi all,
I am contemplating using an mbed as a realtime ROM emulator. My idea is to latch the address bus of a microcontroller causing an interrupt on the mbed which should respond by putting the appropriate byte from a table onto another latch connected to the data bus from the controller. The microcontroller can not be halted or slowed down but its read/write cycle time is about 2.5 usec. Could the mbed pull this off ?
