Hello,
I have a general question regarding the data bus for TMS320C6412. Please correct
me if I am wrong. If I use any one of the EMIF memory space enable,
ACE0....ACE3, I am accessing 64-bit DATA, is this correct?
I am planning to design a board using TMS320C6412, I would like to send/receive
64 bit external data. I am not doing any memory interface, so I don't need
any control signals. My question is if I am writing to any EMIF memory space 64
bit data, I should see 64 bits on the data bus.
Hope my question is clear, if not, please let me know.
Thanks in-advance,
-Y

The EMIF performs memory accesses [to memory devices or a peripheral
device, FPGA, etc.].
The amount of valid data on the data depends on your program or DMA
setup - it can be 8, 16, 32, or 64 bits.

Your peripheral device is accessed as an asynchronous memory device. You
will at least need a minimal set of memory control signals like AAWE,
AAOE, and AARE.

If your are performing a 64 bit write to any EMIF address space, you
will see 64 valid data bits.
