dwh,

Thanks for your reply. What type of throughput have you achieved (MBytes\S) with your UART-to-Avalon-MM and FTDI FIFO-to-Avalon-MM master components ?

I assume that the FX2 would be able to acheive a much higher through put using its GPIF - 16-bit interface. The data sheets claims 96 Megabytes/s ! We are hoping that we will be able to program the 8051 so that it can directly map to an internal memory within the SOPC system.

Do you have any suggestions or comments on this ?
