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 IRQ 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?
In fact above should not restrict to the ADI dsps. There must be a general manner taking care of the communication of FIFO and dsps for all the kinds.
