AndreiGrozav a7f5746afb ad_dds: Add selectable phase width option. 2018-07-18 18:19:30 +03:00
AndreiGrozav 7b553997ab Add ad_dds.v
It will act as a wrapper for the previous dds modules(phase to angle conv.)
this module will furthermore contain the phase accumulator logic.

AndreiGrozav 2c1f9193cf ad_dds_1.v: Fully use the selectable data width feature
Update for the parametrized ad_mul module. This will scale
a selectable sine width in a multiplication module.
Rename the data and phase width parameters for legibility.

Istvan Csomortani 9055774795 all: Update license for all hdl source files
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:
