Sending coefficients of degree 1000 from UART to custom logic with Nios II and SOPC.

Does the logic actually need all 2000 coefficients during the same clock? How fast does the calculation need to take? What calculation are the coefficients used for, eg., a digital filter (if GF3 is supposed to mean something, post a link to details)?

These questions are important as they determine whether your logic can be serialized or has to be implemented in parallel.

Given that you are transferring data via a UART, I suspect you do not have a requirement for high speed.

In either case, you probably want to use dual-ported RAM. The NIOS II processor would write to one side of the RAM, and the logic would read from the other side.
