Part Number: AM6442
Hi TI Team,
Requirement: A53 Linux ↔ R5F IPC must achieve a round-trip latency of ≤50 µs for the shared-memory data exchange of 1KB between a53 to r5f0_0.
We are working on the AM6442 IPC and communicating between the A53 and R5F0_0 cores using a zero-copy/shared-memory mechanism.
We would like to understand the latency that can realistically be achieved using the zero-copy mechanism for an A53 → R5F0_0 → A53 round trip.
Please answer this priority Question,
What is the maximum round-trip performance tested by TI for a 1 KB payload using the RPMsg zero-copy mechanism?
Could you please share the corresponding TI test results/report for the zero-copy mechanism?
Thanks,
Ganesh D
