Hi all,
I'm using a OMAP L138. What is the better solution for interface a ADC and a FPGA with the DSP ? I will probably use a ADC ADS8471 (parallel interface) and a FPGA Xilinx Sparten 6. The FPGA will be used like a co-processor.
Thank.

Can we connect the ADC to DSP ? What is the advantage to connect the ADC to FPGA ?
Yes, you can connect ADC to DSP using uPP. Refer to below wiki.

Your second question, I think it is dependent on the application.
If your application needs each ADC sample to be processed in real time by DSP, then connect the ADC to DSP to stream the sample.
For our case, the DSP processes a frame of sample. So, we let the FPGA to collect ADC samples for a single frame before the frame is passed to DSP for processing.
