create a SATA interface in my C6672 system using processor

I want to create a SATA interface in my C6672 system. For that, I was given 2 solutions:

a. Use c6672 to control TMS320DM8146 DaVinci Digital Media Processor (connect to the C6672 via EMAC)

b. Use c6672 to control TMS320C6A8167 or TMS320C6A8168 (C6-Integra DSP+ARM Processor).

For a, what interface is EMAC? Is it Ethernet MAC? How do I connect the 2 EMACs together? Which pins to connect?

For b, how do I connect the 2 processors (c6672 and TMS320C6A8167 or TMS320C6A8168)? I cannot use PCIe as the 2 PCIe lanes in C6672 is used for other purposes. Any other interfaces to connect the 2 processors together?
