SDRAM is not that hard to work with. If you have limited knowledge about it or if it is your first time using it, you can always find some open source SDRAM controller IP as a reference. Also Xilinx and Altera both come with controller core.
As for external SRAM, their mem size is limited.…[Read more]
It depends. Data transfer rate can be very high since it is FPGA to FPGA and you can always use many data signals to achieve higher data rate. So likely you can dump data from one FPGA to the other without external buffer. (of course you need to consider data assemble and de-assemble…[Read more]
