+ Build both the read and write logic around an FSM
+ Consistent naming of registers and wires
+ Add support for burst lenghts higher than one, current burst lenght
is 64
+ Fix all the bugs, and make it work (first bring up with
adrv9371x/a10soc)
By adding support for partial avalon transfers (data width < bus width),
valid data set size (DMA transfer length) will be dependent on the DMA bus
width only.
The ad_mem_asym memory read interface has a 3 clock cycle delay, from the
moment of the address change until a valid data arrives on the bus;
because the dac_xfer_out is going to validate the outgoing samples (in conjunction
with the DAC VALID, which is free a running signal), this module will compensate
this delay, to prevent duplicated samples in the beginning of the
transaction.
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.
New license looks as follows:
