Hi all
In a single board, Blackfin BF533 processor is connected sdram 1.
and in the same board Tiger sharc TS201 is connected to sdram 2.
One fpga is connected in between blackfin and tigersharc
Suggest the ways in which I can transfer data from sdram 1( connected to
blackfin) to sdram 2 ( connected to tigersharc) and viceversa thru FPGA
Thanks

SDRAM data transfer between Blackfin & Tiger Sharc

Hi,
How is the FPGA connected between the two? If you include the EBIU on the
BF side and the cluster bus on the TS side, you can memory map the other's
SDRAM. This would mean that you would have to create an SDRAM controller in
the FPGA. The simplest (from interface perspective) would be to have some
code running on each processor that gets data from the other side (maybe
to/from Link Ports on TS side and PPI/SPORT/ASync bank on BF side) and
places it into SDRAM (maybe with DMA).
Is the board designed already? If so, you ask the developer, as they
probably had something in mind already.
Cheers,
George
