We use 2 frame buffer IPs in our design.
1- The first frame buffer: takes its data (din) from DVI Input IP (VGA_IN_INST) and writes this data into an SDRAM through the SDRAM controller. We do not use the read & dout of this Frame buffer . So, these unused interfaces are connected to an empty dummy component (reference to the service request no. 10773449 )
2- The second frame buffer: should read the data written by the first Frame buffer in the used SDRAM and gives this data to the DVI out IP (VGA_out_INST). W e do not use the write & din of this Frame buffer. So; these unused interfaces are connected to the same dummy component.
Taking into consideration that, the dummy component interfaces are Avalon.
Kindly advise about the following
1- Is it applicable to use a Frame buffer to write data in SDRAM and another Frame buffer to read this data from the same SDRAM as described above?
2- How to make sure that the second frame buffer reads the data from the same addresses used by the first frame buffer for writing in the SDRAM? This question is because the addresses are nit indicated when we instantiated the frame buffer in SOPC builder

hi:
are you still focus on studing the transmitting video signals though ethernet to pc? I have just realizing sdram data transmitted to TSE_MAC by SGDMA to PC, now,I want to save the video data to SDRAM ,now I refer the demo :VIP and want to make it as a start project ,but I find the software is complex... so ,I hope to communicate with
you.my email is
