Communication method between BF609 and ARM

Hi,

Yes you are correct Linkport or PPI can be used for high speed communication.

The ADSP-BF609 processor has four dedicated link ports. The ports can operate at up to 83 MHz.

Link ports allow the processor to connect to other processors or peripheral link ports using a simple communication protocol for high-speed parallel data transfer.

Link ports can operate independently and simultaneously, allowing glueless high-speed connectivity of up to four external processors.

The 8-bit-wide link ports can connect to the link ports of other DSPs or processors. Link ports are bidirectional ports having eight data lines, an acknowledge line and a clock line.

The PPI supports direct connection to TFT LCD panels, parallel analog-to-digital and digital-to-analog converters, video encoders and decoders, image sensor modules and other general-purpose peripherals

Hi Anand,

Thanks for your help and reply. For the implement of this kind of communication method. Do you have any code example or hardware examples? Not limited to bf609, any dsp connect to arm is fine. 

Thanks,

Alvin

Hi,

Example code for  EPPI is available in below link,
