Istvan Csomortani a993eefe57 avl_dacfifo: Grey coder/decoder integration 2017-05-25 15:12:14 +03:00
Istvan Csomortani 14a058195d avl_dacfifo: Add avl_dacfifo_byteenable_coder

Istvan Csomortani 81fa65cd51 avl_dacfifo: Few cosmetic changes on avl_dacfifo_wr
+ avl_write_transfer_done_s is a redundant net
 + specify the net state explicitly on if statements
 + to define the edge of avl_mem_fetch_wr_address signal,
its register and its second sync register should be used

Istvan Csomortani 398619d866 avl_dacfifo: Add support for MEM_RATIO 32 2017-05-25 15:12:13 +03:00
Istvan Csomortani 04f397f688 avl_dacfifo: Fix a few control signals
+ avl_last_transfer depends on the avl_xfer_req state

Istvan Csomortani 8f9cadb017 avl_dacfifo: Fix the avl_write generation
The asymetric memory has a 3 clock cycle delay on its read
interface, therefor the minimum distance between two consecutive
avalon write should be 3.

Istvan Csomortani f456ebc6f0 avl_dacfifo: Few cosmetic changes on avl_dacfifo_wr
+ all net names should have a *_s postfix
  + avl_burstcount is a constant 1, no need for an additional
register for it
  + all CDC should have two synchronization register, add
avl_last_beat_req_m2

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:
