I recently changed my board from Texas Instruments to Analog Devices. I would like to see the possibilities with this ADSP21489 EZ-Kit board.
I would like to interface the board with external ADC/DAC.
In my previous board from Texas Instruments, I use something called External Peripheral Interface wich is a high-speed parallel bus for extarnal devices or memory.
I took a look to the datasheet of the ADSP21489 and I would like some advices to do what I mentioned above.
Do you think using AMI (Asynchronous Memory Interface) could be an idea for this?
Could I get the data from A/D and sent the data to D/A faster by SPI? (knowing that I have a Serial Control on my ADC board)
Does the SPI allow us to effectively "overlap computation" with the communication?
Ideally, I would like 2 chip select to control both ADC and DAC.
Please let me know what you think about it.
