Hello,

I would like to know if a FPGA could use the shared RAM (128K) of the C6748?

Where could I find documentation on the way to access this RAM and on the access latencies?

Regards.

Laurent.

Laurent,

Yes, an FPGA can be setup to access Shared RAM through HPI. Aspects of latency through the system interconnect are discussed in the wiki articles:

Check out the Linux SDK for Chip Support Library for HPI. There may not be an example but you should be able to get started using the TRM (Technical Reference Manual).
