5515 DMA for 16bit A/D converter

Other Parts Discussed in Thread: TMS320C5515

I want to know the concept about a DMA interface between a 16bit ADC with parallel interface and TMS320C5515. I guess only DMA interface can handle the data transferring rate  between ADC and DSP because this ADC runs at 3.0MSPS.

Please tell me how to build the parallel interface between ADC and DMA of TMS320C5515.

Thanks,

David

    The parallel port  we normal used in C5515 is EMIF. I don't know what your ADC looks like, but if it has some kind of memory mapped interface, then it should be able to connect to EMIF. EMIF is used to interface to the External Memory device. And EMIF can use internal DMA engine. Please refer to the EMIF user guide for details.
