Cyclone III / IV with ADSP21469 DSP

Hello,

i would like to connect the Cyclone and the DSP on the same lines (Data bus , Address Bus , Rd , Wr , etc ) to the same Flash ( both the Cyclone firmware and the DSP software will be in the Flash ) , my questuion is - can i do it straught forward or i have to do something special at the connections between them , it is important to know that the FPGA is configured first and only after that it turns on the DSP power supply .

Thanks

Dotan
