C6748 EMAC module question.

Other Parts Discussed in Thread: TMS320C6748

Hello,

I'm using C6748 for network application with CCS4.

There is a feature described om the TMS320C6748 Technical Reference under the EMAC module description chapter, at 17.2.2 Memory sub-chapter:

"..This 8K local memory holds enough information to transfer up to 512 Ethernet packets without CPU intervention..."

Can you be more specific and clarify per what time unit these 512 packets can be transferred?

Thank you.

Can you clarify your question? Do you want to know how soon the packet is transferred once it is placed in the CPPI memory?

Exactly. I want to know if I all these 512 packets are placed in CPPI memory, how soon do they arrive to the next side of the network.

If it is not a matter of time unit, can you explain me please, how does this CPPI memory feature helps me to increase performance?
