Hi I am currently working with ADSP-21160N, what is the best possible way to connect spartan 3 FPGA with its DPRAM
Are you going to design a new system? In that case we would suggest you to choose our latest floating point SHARC processors.
BTW, you would use external port in the ADSP-21160N to interface the FPGA. The external port supports asynchronous, synchronous, and synchronous burst accesses
