Hi,
I am using the C6747.
I am serving an asynchronous FPGA with EDMA through EMIFA.
The EMIF (100MHz clock) is configured with hold = 1, strobe = 3 and setup = 1, both for writing and reading.
The EDMA configuration is the same for the writing (from internal memory to FPGA) and the reading (from FPGA to internal memory) operation as well.
I noticed (by checking the WE and OE signals with the oscilloscope) that the time required for writing one 16 bit data to the FPGA is about 70ns, while for reading 16 bit data it takes 140ns!!!!
Any idea about the reason of this difference ?
Thanks,
Sara Salvador
