DDR4

Note

You will have to provide your own board files to use DDR4. See getting started.

DDR4 parameters

To use the tile memory manager, set the parameter below in your Perl script:

#- ddr4 parameters
$param{'ddr4_flag'} = 1;

Vivado IP DRAM 

$param{'vivado_ip_dram'} = 1;

Adds your provided DDR4 files to the project. See:

  • mosaic_2x2_ddr4_8cache_vivado.pl and mosaic_2x2_ddr4_pkt_vivado.pl for an example WITH this param enabled.
  • mosaic_2x2_tile_mem_mgr_vivado.pl for an example WITHOUT this param enabled.

Optionally, you can also set:

#- Yes, Tile memory manager
$param{'ddr_cache_lines'} = 8;
$param{'ddr_init_file'} = 'test_tile_nop.hex';

ddr_init_file allows you to provide hex file firmware for the tile memory manager.
