how to read data from fifo without address bus?

Hi there:

I have a design with ADSP21369 reading data from FIFO connected via AMI. The FIFO I am using comes without address bus. The full flag of FIFO is connected to the IREQ of ADSP to trigger the reading. I am not sure about its memory mapping. I guess I still need the Msx to select the memory. But how to mapping the memory if there's no address bus on FIFO and how can I control the data flow? And in order to speed up reading fifo data into the core, I should use the DMA mode, then how can I configure the start and end address?
