Deprecate unused parameters.
Change to MEM_SIZE_LOG2, to support only power of 2 storage sizes for
now. However in the future we might want to add support for non pow2
sizes so register map is not changed.
Change transfer length to -1 value to spare logic.
Change FIFO interface to AXIS to have backpressure, this allows the
implementation of data movement logic in the storage unit and let the
FSM handle high level control an synchronization and control the storage
unit through a control interface.
Refactor FSM to have preparation states where slow storages can be
configured and started ahead of the data handling.
Make bypasss FIFO optional since in some cases causes timing failures
due the missing output register of the memory. This can be targeted in
a later commit.
Hook up underflow/overflow to regmap useful in case of external memory
where rate drops due misconfiguration can be detected.
Cleanup for verilator.
Scripting:
Add HBM and DDR external memory support using util_hbm IP
Replace asym_block_ram with util_do_ram IP
This commit adds a new synthesis option to the design, that controls
whether an internal clock domain crossing will be generated. Disabling
this option allows you to use a synchronization signal that is
synchronized to the write clock domain externally, and possibly shared
between multiple devices.
The default value retains the old behavior.
